weather condition you Florida people don't know about. It gets COLD
there. It's been mentioned no one south of the Mason Dixon line should
use the wax paper trick for epoxy. The kick-off temp of the epoxy in
warmer climes is enough to melt the wax in the paper and give the epoxy
a wonderful bond to the underlying paper. I had the same problem once
in my New York apartment one hot summer day.
If the temp is right, wax paper is just so convienent to use. Comes on
rolls, convienent width, and comes with a cutter in the package. And
cheap too! But any tough plastic sheet should work, just pick a thicker
material so it can stand up to a squeegy running over it.
- Robert, I used 4" fiberglass tape with epoxy, covered by wax paper,
spare plywood and then old barbell weights to butt joint the sides. I
did one side of each side piece at a time and supported them on a make
ship table of a 1/2 sheet of ply supported on saw horses. The wax paper
worked fine for me although I did spend what seemed like an eternity
fairing all the joints inside and out. For the bottom I used 1/2" ply
on the inside of the butt joint bonded with thickened epoxy. I held
this together during curing with clamps and temporarily intalled drywall
screws. This was much easier than the sides and at least eliminated the
fairing on the inside. I would definately go this route in the future.
