Quarter panels, let's cut em off and put new ones on.

It’s a tool that creates a flange, or a step allowing for an overlapping edge for the replacement panel to fit flush with the existing metal left on the car. Highly recommend one if you’re gonna be doing patch work or panel replacement. YouTube has videos.
There’s a couple types, manual or pneumatic. Highly recommend the pneumatic ones but stay well away from the harbor frieght and central tool ones. I broke 4 of them on 1 quarter. Eastwood Products sells a good one for about 100 bucks. There’s also several on Amazon.

I have had nothing but good luck with the harbor freight flange tool.
I have had mine for over 5 years now, it has put alot of 1/4 panels and patch panels over the years.
Either the quality of them hit rock bottom, or maybe you air compressor is saturating the air lines with water.
Moisture is hard on any air tool, I have three water catches on my air line, (hard plumbed in the garage). So I do not have a moisture issue.
