Should I wet sand or dry sand primer?
When Should You Wet Sand? It’s best to wet sand when you’re looking for a super smooth finish, or when sanding is going to create a huge mess, and you’re willing to spend a long time sanding to avoid that. If you have a lot of material to remove, then dry sanding is probably a better choice.
Should you sand between coats of primer?

Sanding between layers of clearcoat is also not recommended. Wet sanding and polishing the final layer will yield a better result than doing it between each coat.

Can you wet sand high build primer?
Usually if I use the high build primer, I use it first, block with 180 and then re prime with some Primer Surfacer instead of the Primer Filler, then wet sand with a paint stick and 400 grit. 400 Grit will work fine for primer and you won’t have to worry about sand scratches in paint.
How long before you can sand high build primer?
While the tech sheet says you can sand and paint after 2 hrs I would not do it until the next day at the earliest. The longer you leave it the lower the chance of any shrinkage, although it’s not a straightline probability.
