I just used 5200 to seal up a crack in a non-critical plywood
bulkhead. I'm letting it set up for a few more days before my plan to rough it up and glass over it with cloth and resin. I went to the only local marine
supply shop on the island yesterday looking for a small fiberglass
kit. They had one in stock, a pint of resin, tube of hardener, square yard of cloth, etc. I bought it. Everclear, or Evercoat, something like that.
When I got home I noticed it's polyester resin. All my old surfboard building days and afterwards I always used epoxy
resin, so have zilch experience with this stuff.
The smallest amount of epoxy
resin I saw at the store was a gallon of West Marine
stuff, but I am not really interested in buying
that much. Its all expensive here. The kit was almost forty bucks. A half pint should do me for the first coat, with enough left over to add another layer if I feel like it needs it.
Do you guys know of any issues putting polyester resin over 5200?
