Yep, blistering is worse in warm climates.


My Peason Flyer just purchased from Connecticut had zero bottom blisters but
was covered in blisters at the trailer pads from sitting on the trailer for
4+ years. The carpet on the pads never dried out.

I used a black water barrier / coal-tar type product on my last Flyer and
that stopped all the blistering. Water could not get past it to the
gel-coat.

If you're going to put on a barrier coat, then it's smart to take the gel coat
off. All the gel coat is, is a quick & cheap attempt to seal the fiberglass
laminate. The fact that polyester resin is permeable to water, no matter how
much wax you dissolve in it, makes it only marginally effective. No point in
leaving it on there. Plus it makes the barrier coat more likely to flake & peel.
