Switched from a DA sander to a longboard for blocking 3 months ago
I used to think I could block a panel flat with just a DA and some patience, but after fighting orange peel on a 2018 Civic hood in my shop, I grabbed a 3M longboard and some 180 grit. The difference in panel flatness is night and day, I'm getting way less pinholes now too. Anyone else made the switch and felt like they were sanding wrong for years?

Facts, the longboard totally changed my game too. I was the same way with my DA, thinking I could just muscle through and get it flat, but nah, that thing just floats on top of the high spots. Once you feel how a longboard cuts through the material and actually knocks down those peaks, you realize the DA was just wasting your time on a lot of panels. Plus the reduced pinholes is a huge bonus since you don't have to spend as much time on primer. It's like the tool is finally doing the work instead of you fighting it.

Longboarding the final passes with 80 grit is the cheat code for killing those sanding scratches before primer. I don't even break out the DA until I'm at 180 now.
