Saturn Vue Paint Repair Problem

[LoudxB]

Hi all, i'm back again for some more advice. Recently i was offered a side job fixing a few deep scratches on a Saturn Vue (rear door panel and quarter). I asked a few local body shop owners that i occasionally do work for about it and they both told me don't touch it. They said the paint will keep peeling back. I ignored the job request for about a month but my greed overtook me and now i started the job. Ground down the scratches and put on some filler. It didn't take long for me to figure out that my friends were right. Even my filler started to peel up. Eventually i got it all sanded down and i primed it using a heat gun to cure the primer to avoid further peeling (this took forever with multiple layers and sandings). I've taken a break from it for the moment but i need to figure something out. Are these panels basically not paintable? It doesn't make sense to buy a brand new unpainted panel then paint it just to fix a small scratch?

As anyone who works on Saturns will tell you if you get your primer, or basecoat on too wet your in for a problem that is sometimes very hard to correct.

One trick if your base starts to lift it to go ahead and put your clearcoat on to "lock it down".
This will give you a good surface to sand on and recoat without fighting a peeling surface.

Saturn's have been a problem since day one if you break through the factory paint on the plastic body panels.

If you are trying to just repair deep scratchs, next time just scuff the surface with 180 or 220 grit paper and apply a coat of USC 26006 Icing filler.
