[Shop-talk] hot tub refinishing

[ericm at lne.com]

Hi Shop-talkers.

I have a cheap hot tub with a fiberglass tub.  The gelcoat
on the fiberglass is cracking.  I'd like to get a few more
years out of it.

Can I just buy epoxy and brush it on?  Will it smooth over
reasonably if I do so?  I know it won't be like it was popped
from a mold but I dont want it to have bad brush marks.
Any other hints/tips/tricks?

Thanks!

Eric
