Final sanding 400. Wet or dry???

[Tony1968]

Can someone explain the difference in sanding dry 400 versus wet ? I've watched quite a few videos and wet sanding with 400 looks like the final results are cleaner. I have the paper. I just want to do what's best. Opinions welcome and thanks.
This is on final round of hi build. 320 is complete.

Dry makes a lot more dust and clogs papper way faster. However dust blows off fairly easy. Wet cuts smoother and doesn't clog as bad but it creates sludge that gets in places you didn't know existed. I do both depends on what I'm doing. Sometimes I do prep work with a da and 320 lol all depends on the job I'm doing

I am in a dusty dirty quagmire now and cannot see it getting worse. I think I'm going to do a massive cleanup then give wet a try. Thanks guys. Plus not having to wear a dust mask seems like a plus to me especially with 90 degree temps.

I personally wouldn’t stop at 400, wet or dry. I finish all my stuff in 600 wet. You would REALLY hate to see sand scratches in your finished paint after all this work.

When we did my Camaro we sanded the primer 220-400-600wet. Yeah its a bit of a mess but like D said absolutely no scratch marks. Also clutch is absolutely right about the cutting and clogging

I'll take it to 600 after the 400. Thanks.

100% agree but I fix a lot of junk. Even then on fine metallics or pearls I do the same I may even go 800 1200 or 1500 on blends just to be safe but again what I'm working on and the color has a big part to play in what I do.

Agreed, especially on blends. But for a complete like what Tony is doing, 600 should be sufficient and as far as he needs to go unless he’s going with some crazy metallic.

Going with a very simple solid white. No metallic for my first spray job.
