Hot coat poly or eppxy

Hi guys

Just a question for the glassers out there.
Just finishing off my sup foil board.
 I was just wondering if I could use polyester over epoxy just for the filler coat? Any advantages or disadvantage ?
cost is a big one for me and drying time.
I was just wondering if it cracks or delaminates etc.
I will rub the board first for it to key.
Cheers

No.

It’s been done not as a filler coat, but as a second gloss coat, just to get the shiny poly look. People stopped doing this because the flex rate is different between the two, causing delam.  Today, glass shops clear coat with paint to get the glossy look.

Thanks Dwight

I will stick with epoxy then.

I did it on the F18 downwind board I mostly reskinned. Never again. Came off in chunks a month later. The board is sitting behind my shop in the weeds waiting for me to do something else stupid with it.

I'm sold thanks Bill, I have just used epoxy.
Not to long now and she will be finished.
