Hey swaylocks - I am just finishing my first board using foam / epoxy..So I am stoked to be finishing this thing up.. Its 7'5" x 3.25" x 21". 6 oz with a deck patch on the top 6 oz on the bottom.. Trying for a bigger guy intermediate floaty board that isnt too stiff - hopefully will be able to duck dive this thing somewhat - I weigh 240 lbs and am 6'4"..
I have had a heck of a time sanding this thing - multiple burn throughs, my piece of garbage harbour lights sander would speed up randomly when applying pressure. So I've had to go through and patch some of the burn throughs a couple times already. I got a different sander and that seems to be working out, but I am still at a place where there are some slight thin spots in the glass - if you look from the right angle you can see the fibers underneath, and if you push on it hard you can tell there is minor weak spot. TBH I just want to be done at this point and I am not concerned about cosmetics - are slightly thin spots going to cause a problem if I ignore them? Can they leak? It seems like it'd be watertight, not extremely visible / the thread is not fully exposed.
I am thinking about some of these options 1. leaving it as is 2. spray painting it with enamel spray paint as a final seal coat (thats just what I have on hand) 3. trying to do a gloss coat with epoxy, maybe thinning it out with denatured alcohol?. 4. go through again and just coat the slight burn throughs with epoxy and sanding it again.

Much thanks for any ideas you have.
