Frame Painting For Newbies
Hello everyone! I'm looking for guidance regarding painting bike frames.
Project:
I currently have 3 old (1960's, early 1970's) Schwinn Cruisers that I'm in the process of restoring. While I would love to restore one of them to its original specs (original paint, stickers, etc), I know it won’t be possible. I'm saving that particular bike for when I either become comfortably proficient with painting, or I can find a professional restoration expert.
I would like to take the time to learn how to paint these bikes so that they look good. For one of these bikes I'd like to customize it (frame and fork will be the only original parts; all other parts will be aftermarket). This bike looks like it has been spray painted several times by the previous owner, so I'm looking to remove all the paint and give it a custom (non- factory original) paint job.
I'm starting from scratch. I'd like to find video tutorials on painting bikes, advice on spray guns, nibs, etc.
I tried searching for businesses/shops that specialize in bike painting, but they either don't get back to me with a price, or (the online shops) the prices are way more than I can affird ($700+). I would much rather buy the equipment and learn to do it myself.

You don't indicate your location. Have you considered powder coat? Schwinn cruisers weren't exactly known for their fine paint jobs, and I think a powder coat would be a good match.

This is a Schwinn American that I stripped the paint on, pained it first with Rustoleum rusty metal primer then Rustoleum Aluminum paint. Then waited a week and sprayed it with two cans of Duplicolor Chrysler Intense Blue to mimic Schwinn's Sky Blue. It is real close. Some say an exact match. Don't remember who I got the decals from, but I remember them being water slides. Over this will go a two part clear coat. I have a gun and compressor however, there are 2k sprays available in spray cans if you don't have a paint gun and compressor.
I liked Schwinn's Flamboyant paints. They looked good and they have that '70's look if that is what you are going for. I've also come to appreciate their solid colored paints as well. Not as flamboyant as their Flamboyant paint, but still good looking.
I also painted this Schwinn Continental with Campus Green paint.
It was decaled and then clear coated with a two component automotive clear coat.
I also have a Schwinn Heavy Duti that I painted with Rustoleum Rusty Metal Primer then Rustoleum Black. That was done 40 years ago ago, and it still holding up ok.
Duplicolor paint is expensive compared to Rustoleum but it is better. They do have good colors and they have spray nozzles with a fan pattern rather than the traditional cone pattern of most spray can nozzles. I did notice that Rustoleum has an indexting nozzle system on their new spray paint cans. I also bought House of Kolor paint that TCP Global packaged into an aerosol can for me. I used Aluminum colored paint for the flamboyant base (again) and it came out great. Excellent paint even in a spray can. Beautiful color and easy control with the nozzle provided.
The frame builders here can fill you in on paint guns and compressors. I have an amature set up that works well for me. I bought my spray gun from TCP Global as well.

I'll second the recommendation to have it powder coated. My local powder coater charges around $150 for a single color with clear on a frame. That includes stripping any finish that is already on the frame.
Painting a bike frame is not easy with a spray gun. There are a lot of tube intersections that will easily get overloaded with paint and run. There are also spots like the underside of the seat tube/seat stay junction that are hard to get paint into, especially with a large automotive sized spray gun. I have painted a number of frames with this detail spray gun from Harbor Freight tools. https://www.harborfreight.com/adjust...tail+spray+gun It works fine for a $14 spray gun. I use base/clear paints from TCP Global. Spraying the base is pretty easy and there is not much chance of runs with that. The clear is where you have to be really careful not to get runs.

Nikon, what area of the country are you located? i'm a pro builder and painter that hangs out here sometimes. Done right, wet paint is the ultimate look. Even doing it yourself it can be expensive just for the materials. I like to use House of Kolor paints because it has all the best options. "painting" should really be called "sanding" because you will spend a lot more time in prep than spraying.
To describe all that is required to do a good job is a bit more than most will be willing to read so i'll just skim the subject. After getting rid of the old paint (or sanding it well down) primer is applied and then sanded. Next I apply a sealer. This helps cover up bare sanding spots and provides a consistent undercoat for the color coats. And it helps with adherence too. A chip is most likely to occur between the primer and color coat rather than between the primer and bare steel. After I put on the color coats, I apply some undercoat clears that protect the color and when sanded provide a smoother surface for the top clear coats. This is when decals are applied and they will probably require their own clears to bury them so they don't leave an edge. And finally the top clear coats are applied to give that glossy appearance. Sometimes if one makes a boo boo the final clears can be buffed out. I use very fine sandpaper and 3 grades of buffing compound for that job.
Because I am a pro, I use pro grade spray guns (I have 7 or 8). It is possible to get a good quality one in the $100 range if your budget is tight. And it can be used for all the different paints if you choose a 1.3mm nozzle size.
I have 5 Chicago made Schwinn Super Sports in my shop some of my local students are using to learn how to paint (I teach painting as well as frame building). H of K has paint that closely matches the Schwinn colors for the 60's and 70's.

Doug gives a very good if short description of the process. The big factor, IMO, with painting is balancing the expectations with the abilities/budget. I have had Doug paint a few of my bikes (and I will say he was painting as I did all the sanding and prep) because I do want the best looking result and also have good durability. The two part paints he usually uses (HoK and the beloved Imron) can have a deep luster and the chemical curing hardens the paint so chipping is less than single component paints can attain.
The tooling costs are high for this method though. Air compressors (and the electrical service capacity), air lines and oil filters, spray guns and cleaning products can be more than a few hundreds of $. The paint, it's hardener and primer won't be cheap and likely will only be available in quantities suitable for a dozen bikes. Then there's the practice time and consumables to get comfy enough to try an actual frame.
The far more common way newbie/home painting is done is with spray can paints. These paints and primers are available in single component low cost versions (like Rust-Oleum) or two part paints (the can has the two components separated by a barrier which one breaks and then shakes the mix up before spraying) more often found in the automotive paint supply stores. Without a doubt these two part paints are more durable than the cheap single part paints but a single can costs 2-3 times what the cheap stuff does and the working time of the now mixed with the hardener paint is limited. For a best job with these paints/primers figure on needing a can+ per layer. Count the layers and do the math.
As Doug mentions "painting" is really far more about the prep than the tooling or materials. To get the results you see proudly shown here and on line takes a lot of time. When Doug has painted my frames we took a week working near full time on them each. A pro will reduce this time as they are far more efficient as the prep work than I am. A total newbie would likely take longer than I do. The actual time in his spray booth for all the coats was less then 2 hours over the week.
(Although one aspect of the "how long to make a ..." is that one gets better at seeing stuff sooner than one gets better at doing the work, early on. I kept track of my hours to make a frame early on, at around 25 hours (before paint). Now 45 years later I take 2-3x longer as my skills of making my job easier are not as refined as my ability to see how the brazing/mitering/finishing looks. This is one of the reasons why I have never hung out my shingle). Andy

Harbor shows a nice little sand blaster for cheap. 18 oz. Portable Sand Blaster Gun Kit (harborfreight.com)
On their detail sprayer, it seems like a prudent idea buying a 2nd unit. Spare parts and canister and all.
Great tips on this thread. The thing that worries me most involves creating the proper desired color.

my limited experience is that it cost way more than you would think to paint a frame and it is lot of work to get it to look good I would go powder coat
also spray paint from hardware or auto stores can may a great looking result, but it will not be as durable as if you use auto paint. (depending on wear you live you can get auto paint put in spray cans)
good facemask with filters is first purchase (60 buck or so and my not be really enough for auto paint)
paint stripper
degreaser
rags, brushes, sand paper ,tack cloth gloves, miscellaneous
sprayer of not using spray cans (I used a pre-val sprayer one bike to spray auto paint)
acid etch primer, sandable primer, color coat, clear coat
easily 150 to 200 before auto paint
that is what I recall anyway

- take bike all apart
- strip paint, anything left will show
- degrease
- mask
- acid etch primer
- sandable primer
- sand, may need to do another coat of sandable primer
- color coats 2 to 3 with proper respray time between
- clear coats 2 to 4 depending again proper respray times
that is what I recall anyway

Well, it seems that Nikon Fan posted on 9/5, and hasn't been back since 9/6. Funny how that works...
I was going to post that painting a bike frame is no different from painting a car. All the materials, and process steps are the same. Only difference is the shape of the object being painted. I'll stop here, since our OP apparently has better things to do than read our responses...

hi there. i have seen a lot of TITANIUM COLOR bike frames out there, painted alloy frames, not actual titanium material frames.
for exaample the FNHON GUST and STORM models of folding bikes, they come in this awesome TITANIUM COLOR.
does anyone know what colors (varnish) to mix to get this look?
i have looked everywhere on the net and youtube and cant seem to find a tutorial.
i thank you in advance!

Plastic Sheeting Paint Booth
Unheated all wood garage in the PNW...
It's all about heat containment...
Step inside... The booth is on the right...
No need to heat this space, but it benefits with the residual heat knocking down the chill...
A peek into the booth...
A constant 65 degrees inside with a radiant electric heater... Loving this...

I've done similar to what Paul shows, plastic sheeting walled in space for fume control. In my case it was for brazing smells though. I now have a casement window mounted exhaust fan (bought from McMaster-Carr with a louvered weather cover) now that pulls far more air than past efforts did. Before I had a plywood board with a couple of axial flow cooling fans mounted and while they were better than no exhaust fan a proper one is so much nicer.
Here's a shot of the paint curing box I made. It worked really well for the couple of frames I've done paint work on since. In my unheated garage, during a 36* winter day, the box's inside temps got to around 150*+. Being made of PVC, Coroplast and Zip ties I can collapse it down for storage or travel. I had the heaters already and spent about $120 for the plastic stuff. Andy.
