I'm getting near the end of building a Penobscot 14. I'd like to paint the outside and finish the interior bright. The wood is sealed with two coats of Clear Coat from System 3. System 3 sells some paints compatible with their epoxy, but I'd rather purchase something locally rather than have to wait around on a mail order if I run low (just had that problem with epoxy). I remember another thread where household latex paint was used, and seemed to work well. Has anyone had any experience using varnish such as Epifanes, Z-Spar, or something similar over epoxy, and what surface preparation is necessary for the varnish to stick?
Thanks for your help.
