I’m in the middle of my build. On page 121 it states that “one thing you don’t have to sand off: epoxy stains”. So I left these stains, they were cleaned with denatured alcohol(before curing) and sanded with everything else. when I applied the epoxy and fiberglass the stains have remained visible! I have not added any more epoxy to fill in the weave. finally we come to my question…..Will the stain disappear magically as I add epoxy or will I have to look at this staining for the rest of my life as it is entombed under the fiberglass???
I am vexed by the possibility of this being permanent and very disappointed that I was instructed to leave it there
It’s difficult to tell exactly from the photo, can you upload another with less glare/ direct light?
As long as you are wetting the fiberglass all the way through to the wood it should blend in with the “stains” from previous steps before the epoxy even sets up. If it doesn’t blend in at the wetting stage then you may not be fully saturating the glass.
Second what Adam said. If properly wetted the glass is transparent and the wood darkens and the existing epoxy streaks blend in. Your wood doesn’t look like it got wet. The next epoxy coat won’t be able to penetrate the first coat. The existing “stains” will stay visible, but maybe more concerning is the question of if the glass is really adhering to the wood.
