Congrats. Recently retired myself. Probably will have to trade my '18 Silverado in a couple of years for lack of paint. Or maybe work on some kinfolk cars.
They put LED's in our shop, not impressed. Very shadowy, not any brighter. Probably saves the company money though. Do your math. X2 on the garagejournal site.
Lacquer thinner works on painted pin stripes. I guess it depends on the paint that was used.I used Easy off on my drag car and trailer years ago and it worked fine. My wife crashed my Silverado last fall. It had pin stripes so I took the old door home and experimented with it. Easy off wouldn't touch it so based on our body guys advice I tried lacquer thinner and it took the stripes off easily. Neither harmed the clear coat.
I'm not a body guy but from my understanding, clear coat needs to be put down over a fresh color coat. The color coat will still be slightly wet/tacky when the clear is applied. Chemical bond. But fell free to correct me if I'm wrong.
