The build manual says three coats on the outside; I have three coats and have some fiberglass cloth grain that appears to be visible so I’m going with at least one more coat.
I built the storage box first and I know I went too thick in a lot of areas because I had a lot of trouble with runs. I’m trying to avoid that as much as possible on the camper, so I’m doing thinner coats. Does this result in a rough finish, or will even thin coats tend to level themselves? In other words, should I keep adding layers until it’s smooth, or should I just accept that it’s going to take some sanding to make it smooth?
Trying to add a pic for reference and it’s not working so well…

The first epoxy coat was the heaviest because you need to fully saturate the fiberglass cloth. After that, I did 3 coats with an epoxy approved foam roller. You will need to sand no matter what, drips/runs are easy to sand out. I had some areas that seemed shallow so I spot filled a few of those areas after initial sanding (1-2 coats more).
