Unpopular opinion: blocking a panel by feel beats a guide coat, and my old boss in Fresno proved it to me
When I started at a shop in Fresno, my boss kept telling me to ditch the guide coat and just run my hand over the panel in raking light. I thought he was stuck in his ways, so I kept spraying guide coat on every repair for the first 3 months. Then I got a '17 F-150 bed side that fought me for two days, and he walked over, felt it once, and pointed to a low spot I'd been sanding right past. He was right, and now I use my palm on the final pass before I ever touch a primer. Curious if you all trust your hands over the powder, or is that just an old school thing?

Man, I know that sinking feeling when someone points out a low spot you've been sanding right over for hours... been there more times than I want to admit. Spraying guide coat on every single repair like clockwork can make you blind to what your own hand is telling you, and it sounds like that F-150 was the lesson that stuck. There's something about a palm on a panel in good light that catches stuff the powder just hides under.
