Ok need some help from the hive mind on paint stages for the inside our camper.
So far we have shotblasted if back to bare steel, and given it 2 coats of epoxy primer. Currently rubbing it down with 180grit the plan was to do some minor filling work then flat back for another coat of epoxy as a sealer and wet on wet with a polyurethane enamel.
The data sheet says when using as a sealer-filler to dry sand to 280-320
We only want it protected none of the paint work will be visible.
As it has taken 2 of us 2 days just to flat it back to 180 do we need to go through 3 more rounds to get it to 320?
