Hi WOG
Ill have to look into the glass bubbles since I don't have any and my local West Marine is closed for the ENTIRE month....Didn't even bother to put a sign on the door but its on their phone recording.
So I did some sanding and ended up with a non perfect substrate and decided I was obsessing over this project so I decided to wash her down with acetone twice using painters cotton towels folded into fourths changing the surface area very frequently.
Coat one
I then brushed on no wax gel coat. I found it very hard to work with. It doesn't level at all. So I brushed it up and down then side to side. By then it started dragging so I had to leave it be. So the brush marks stand high like peaks of the Andes. Let it dry for 24 hours.
Coat Two
I rolled on no wax with a premium SW 4 inch foam. Gel coat applied much better with good coverage. Again. The gel coat can only withstand a few passes before it starts to pull. It did not level out either. So the brush marks were only reduced by 40% from the first coat.
My plans for the third coat (tomorrow) is to again roll it with foam roller using waxed gel coat. Lord knows what that will look like...LOL I do know this...It looks a hell of a lot better than yellow UV damaged cracked plastic. But its a lot of time and money to build this console.
I may sand out coat 3 and install a coat 4 if the brush strokes don't go away.
Heating the garage is part of that large expense. The working temp was been between 74.5 and 76.5 I am mixing gel coat at 1.35 % Here are some pics...
