Ok once again i look to you all for a vast poll of knowledge. I am back to finishing my yak. It has sat for many months now so i have sanded teh epoxy so the varnish has something to bite into. Unfortunatley i went into teh glass in a few places and will have to give it another skim coat of epoxy. 1) with fresh epoxy how long should i wait to apply the varnish. 2) using Raka non blushing will I need to rough up the surface again if the epoxy is new? Thanks in advance
