I just thought I would throw this out there. I tried to remove the decals on my 1985 Trek 520 with a blow dryer but it wouldn't budge. I can feel a bump between the decal and the paint but heat did not seem to soften the decal up. Does anyone know if Trek clear coated over the decals in the 80's? I'm thinking of going to Lowes to get some decal remover solvent.
It's not real visible, but I think you can see how the decal on that '82 is starting to peel back. Sounds like yours is clearcoated. On my 1987 560 EX it's definitely clear coated. Fwiw.
That's a good price for that frame.
I'm sure my 85 is clear coated. I'm going to strip this bike down for a repaint. BTW, mswantak at Velographics makes top of the line decals. I have a set of these for the Trek and am highly pleased with the quality. Thanks Mike!
