wet sand it with 220?
are you out of your god damn mind...
you should have searched on here, i explained it before
the same shit happened to me, i bought a used 6 piece WW urethane kit for my first 91 hatch, it had a good 3 diffrent colors of paint, along with some shitty primer...
all the paint and primer was spidered like a mother fucker...
i used aircraft paint stripped(white can with blue accents) and a flat blade mac scraper...
let the stripper sit for 5 to 10 and lightly scraped the lifted layers off...
longer than 10 minutes and it starts to re dry and then you're gonna scrape too hard and gouge it...
so i used the stripper to get most of it off and then i used a PALM DA with 120 on it and just buzzed the rest of the primer/base off...
then resprayed the primer, scotch brite'ed the primer, then based and cleared...
not sure how it held up cause the car was stolen 30 days later... but it looked like glass when it was done...
if the gouges are light then just sand em out, if they are deep i would just use bondo... simple and easy...
if its in a HIGH flex area you may want to consider something other than bondo, either straight fiberglass resin, or perhaps some urethane product that will harden, maybe that m3 window weld that people use to harden motor mounts, but i never tried that..
palm DA - dual action sander, pneumatic...
its gotta be a small, light expensive one...
home depot had an ingersol rand for less than 150 i think, and it looked good...
you def do not want to use one of the big doofy right angle DA's, they are fucking junk...
