Hi,
I'm a new user looking for advice/guidance on how to rehabilitate my old pool. It is a 18 x 36 "kidney bean" in-ground pool installed in late 70's, approximately 25,000 gallons. Concrete bottom with 3.5 foot fiberglass wall panels. Nothing fancy, with a sand filter and 1 HP pump. No salt generator. No heater, just a 16 mil clear-tek solar blanket.

The problem is that the fiberglass panels have quarter-sized blisters (probably a couple hundred over the entire pool). The blisters have been there a couple years (when I bought the house). A couple have popped off, revealing what I assume is the fiber mesh underneath. The concrete is in good shape, but will need painted or something.

I've looked at several different epoxy type paints, with a couple pool dealers saying that they just paint right over the blisters. Is that a good idea? I'm not sure what my options are for this big project. I'm not opposed to a DIY solution, either. Of course, I don't have a ton of money for this, but I'm hoping to find something that would last the next 6-8 years at least. By then, I'm moving!
Thanks in advance for the help!
