Ok, I am starting to do the finish sanding before varnishing. I am using 220 grit wet sanding with a palm sander.
I have sanded in several places too much, where you can see the nap of the fiberglass cloth. I have not damaged the cloth, but you can see it.
I am wondering, do I just put a thin coat of epoxy on and try sanding it smooth?
Thank you for your input
