I've done some research already, and most places said to do a full panel respray for my situation.
I just bought a high mileage 2000 2.5RS and there's a decently sized (1.5" OD) paint chip on my trunk, and two smaller quarter sized paint chips/flake on my rear quarter panels. I tried to feather out the lifting paint on my trunk first. I was able to get the surrounding edge of the paint flake super smooth. I used 220, then 320, and 400 grit sand paper to do so. I washed the area, let it dry, then used a tack rag to get any dust off. Here's my issue: When I laid my first light coat of etching primer from 12" away, the area I feathered started to wrinkle. I figured that I didn't sand it completed, so I redid everything, this time sanding even further out around the effected area. When I hit it again with etching primer, it wrinkled around the edge again.
Is my paint too old, or possibly thin, to be repaired? Before I attempted to work on the affected area I used my hose to rinse off the area; just letting it run down the panel. As I did, the paint would just flake off due to the [light] pressure of the water. Paint would even lift off from blue painter's masking tape... I'm afraid of working on the rear quarters because that's harder to replace. For the quarters, I plan on using some touch up paint and just leaving it alone. I might do some light sanding and shoot some clear on top.
Any tips on how to stop the feathered area from wrinkling? Maybe use a touch up pen instead of a spray can...?
I'm afraid to wash my car at the moment in fear of paint flaking off =(
