Repainting a Bike, Not Stripping
Hi all,
I'm currently working on doing up a nice old 80's frame. I am just working on stripping the paint, I have applied the two coats of nitromors as recommended on the forks and the frame and have spent about an hour and a half working on stripping the paint. But, it's just not coming off on the forks and on the frame it is doing as much damage as it does if I scrape away at the half I have not coated.
My thoughts are, that seeing as a lot of the paint is still in good condition that I spend a bit more time taking off all I can (those parts which are rusty) and then apply the primer, paint and lacquer over the top of what seems to be good condition paint.
Any thoughts?
Thanks,
Sam

Don't mix lacquer and enamel paints. Now that some of the frame is stripped and some is not one of the challenges will be sanding down the transitions so the resulting job looks smooth and nice. Roughing up the original paint can help the stripping chemicals to get a bite on it and increase the effectiveness.

No idea what frame are you taking about but I'm almost sure is an 80s italian one, back in the 80s many manufacturers were using an epoxy primer, that thing is like plastic, it will hide any imperfection in the tubing, then paint over it.
The other thing is that as older the paint the better so doesnt surprise me that the stuff you are using is doing nothing, i dont know the product but there are paint stripper gels that are better than other ones.
If the paint is ok, you can sand it to even it, put new primer sealer over it and put polyurethane car paint over the top and then polyurethane clear, the original paint is too old and probably wont react with the polyurethane specially if the primer you are adding is good.
Hope this helps you.

The last frame I added braze ons to I went over the affected areas with my torch to burn the paint. This made sanding off the paint quicker. I did this outside of course.
