What can I use to fill ground out gelcoat blisters? I have sealed them all with resin and now I am looking for something that has a thick and spreadable consistency like bondo. These are some fairly large areas about the size of a silver dollar or better but not very deep. It needs to be sandable to a smooth finish for painting with a waterproof swimming pool paint. BTW, it's for the frik'n steps into my pool, not a boat bottom. I tried some stuff that is like resin w/ fiberglass in it and it spreads like chit, I need something smooth and workable.
Thanks for any help.

I was wondering who on earth would paint their running surface with a pool paint! I BELIEVE that many use a standard resin and then mix in micro balloons to thicken it.

I was wondering the same thing
West system epoxy resin with their fillers, they make different fillers as far as workability and hardness for sandability. Great stuff!!

I've just used an Interlux 2 part epoxy product made for repairing osmotic blisters.('Course it has plenty other uses too) Comes in a pint size pack, one part is cream coloured the other a greenish blue. Has a consistency like butter, won't sag even on horizontal surfaces and sands beautifully.
