I want to treat the inside of several of my steel bikes for protection against rust. In the past I have used Weigles Frame Saver but can't find it in stock anywhere. I have some Boeshield T9, I understand it is a rust preventative also but not sure if it is as good as Weigles.
Whats your feeling about T9 ?

Seems like anything I want in the way of bike stuff is out of stock lately, thanks Pandemic !

I've known lots of folks who use Boeshield as a frame preserver. You can also go old school and use linseed oil.

Boeshield was developed for Boeing Company as a metal protectant and lubricant: https://boeshield.com/about/
Amsoil HDMP is frequently said to be equivalent to Weigle Frame Saver. https://www.amsoil.com/p/heavy-duty-...otector-amhsc/

I've only ever used the Weigle stuff once, but re linseed oil, my understanding is that as it dries to a (perhaps) more harder or stickier consistency than the spray stuff like Weigle, I'd be extra careful of plugging up the bb threads area to avoid any issues with the threads getting too gummed up with linseed oil and being really hard to clear out afterwards.

I could be wrong on this, but probably worth getting well informed in case this can be an issue.
I put either paper towels or rags well into this area when I did the framesaver thing, paper towels I think, hoping they would absorb more of the stuff dripping down into this area from all directions as I turned the frame around in all positions as I sprayed here and there.
Didnt have any issues reinstalling bb so threads were ok, so I would do the same another time.

"Amsoil MPHD Heavy Duty Metal Protector" is available at most NAPA auto parts stores and is identical to Frame Saver. You get a larger spray can for less cost and it works exactly the same. I am sure Amsoil private labels this product for JP Weigel.

BTW, T9 is available at Amazon but the Amsoil product is better.

I've been using the Amsoil for a half dozen years. I don't know how well it's doing, but all the rust on my bikes seems to be on the outside.

Side note: JP Weigel no longer owns Frame Saver, Frame Saver is now owned by Problem Solvers, which is owned by QBP. I just checked, there is plenty of Frame Saver in stock in QBP's warehouses. If you can't find some in stock locally, your local bike shop should be able to order it for you.

I got some of this stuff at my local home DIY store for under $5. I've used the Weigle product on a few frames and, while I can't promise this works as well, it smells like Weigle frame saver. not sure what that means. I shot a few sparys into my new steel frame just now. will report back in a few years (ha!) if the frame rusts from the inside out.

+1 for the Amsoil Heavy Duty Metal Protector. I use it in all the frames that I build and I don't see any difference between it and Frame Saver, except the cost and size of the can.

Thanks everyone for the help ! Our local auto parts close by carries the Amsoil meta protector. I will give it a try.

I've been using Amsoil MPHD Heavy Duty Metal Protector the past 18 years on my steel bikes. Can and applicator are easy to use and the $8 can does 3 bikes. So far, all my treated bikes are doing just fine.

common sense seems to me that the most important thing is to be liberal with how much you spray in, and be ready to turn the frame every which way and more, to try to get the stuff all over the insides.
I did one section at a time and tried also to spray with a thin long nozzle tube thing in different directions, to help the chances of the product going all over, combined with fast and repeated turning the frame around , imagining the stuff running down inside to try to get it all over.

Fluid Film seems to be the best alternative to Framesaver. Peter Weigle says they tried it while developing framesaver and it doesn't work as well, but I forget his exact objections. Maybe that it's harder to apply. But you can get a wand to apply it in tubes.
