After a long delay in working on my WD 10, I have a question about sanding epoxy. When I glassed the hull (a couple of years ago), I had put on a coat of epoxy prior to glassing. I can't remember if I sanded the sealer coat prior to glassing, or if I just put the glass over the unsanded sealer coat.
Do I need to sand the sealer coat before glassing? Thanks in advance.

Since it has been a couple years, I would do a light scuff sanding, before fiberglassing. If using MAS epoxy , they state anything over 12 hours to do a light scuff sanding. I usually will go 24 hours before doing a scuff sanding and have not noticed any issues. I use 120 grit to scuff up.
