You paint, clear, let the clear curr really well, then put the decals, then another coat of clear over top of the decals You do this so if you mess up the decals, you can remove them without damaging the paint.Any auto body shop can do it.
Man, I saw your bike list and I had the same bike as you. I used to ride on a marvellous electric plum '93 Trek 930 SHX and gave it to my brother.
Nowadays that bike is painted in black because my brother didn't take care of it and its paint faded a lot in the sun. I have both catalogs by Trek depicting my bikes.
Thank you very much for the tips about the paint. Maybe this time I'll take a chance and send it for painting .
