Does anyone have experance with Polyester Resin? I am looking at using this on the exterior of the SUP. I would use Expoy Resin for the interior. I alredy know some pros and cons.
Pros; UV resistant - more scratch restant finish - no need to put a clear coat over but can gelcoat - faster cure time -
Con; needs to be at 65 degrees of hoter to apply - more toxic fumes - short working time - won't stick to epoxy fillers -
Depending on the epoxy base it may not stick well to the epoxy with out using a "tie" coating.
We use this at work. It is highly toxic use high qualiity respirators if you use it, and glove up it also tends to smell foul even in small quantities.
I built a 12-6 Kaholo from the plans for the 14 footer. I used the same frames and only scaled length/longitudinal dimensions. The proportions are very nice and I would do it again.
This summer I saw a little boy, about 6-8 years SUPing a 12 foot board. He had a blast and had no problem with the 12 foot board.
Used numerous gallons of polyester back in the day - now I wouldn't touch a jug of polyester with your 10' pole.
Sorry - I wouldn't even consider using polyester on anything.
