    I'm in the process of scraping off the peeling paint on my 1990 suburban. Why did all these peel like this? What is the problem? The primer underneath is intact, do I need to go down to bare metal? Only the roof is affected, the sides are great, can I avoid taking the good paint off before repainting. What prep work should I do to the primer on the roof? I heard that GM recalled these for this problem, I assume this is too old for any help from GM. Thanks

    For the roof and any other parts that are badly damaged by age I would recommend just sanding the old paint till you get a good clean surface ,doesn't have to be down to bare metal just get rid of all the primer that is lifting. Then spray it with a good primer filler. If the rest of the paint is in good condition you can just use a paint prep solvent and remove all old wax and grime, then scuff or wet sand the rest of the truck down. You should have the whole truck sprayed with a primer sealer before you put on the paint.


    P.S Always use prep solvent or atleast a tac rag before you spray primer or paint on any part of the truck.

    I think they had a new kind of primer in 90 and 91 that had problems with it and it made the paint peel. They repainted them for about 5 years afterwards

    If the primer was faulty does this mean I sould remove it even if it is not peeling? Will the new urethane stick to it?

    When i worked for a body shop back in the early 90's we would take all the peelers down to the bare metal. The problem was with the primer and the shop i worked for was not willing to paint over the defective product! Why do the job twice? The other problem i found was when i masked the area that i was going to paint the tape when removed would some times lift more paint off in the areas that wern't already peeling.

    Goodluck
