I am having problems with the paint coming off the roof and it resists any attempts to repaint it. The primer does not seem to want to take the paint. I guess it is a non-porus epoxy primer of some sort. Is there a primer that will let new paint stick to the old primer? The paint on most of the truck looks pretty good but once water gets between the top coat and the primer it starts to peal. I have been using Dupli-Color which is not the best. The solvents are too hot and it hardens before it has time to adhere. I am trying to avoid painting the whole truck which will cost more than the truck is worth.

Same issue with my 2000 ex! The paint peels! Figuring I need to repaint.
Greenish primer underneath. As you say, seems like an epoxy primer that just won't take paint. Once the water gets under the topcoat just seems to peel. Pressure gun at the carwash started it. Seems particularly bad at the door jambs.
Would be interested if we had similar VINs - you know, manufacture plant, date code.
Its gonna take a new paint job...

 

I am not going to give up yet. I think I need to make a trip to the paint store to get some good top coat that does not dry in 30s. I may have to sand to bare metal and re prime with conventional primer.

You need to scuff sand the old primer, then apply good quality epoxy primer, wait 30 min to an hour, then paint. RM and Dupont both make a epoxy primer that can be topcoated directly without sanding. Hope this helps.
