I think you are currently doing it the best way. On wide surfaces I use the
popsicle stick on its side and apply the epoxy like a grader blade spreads
bitumen on a road. Your 1/2 hour seems about right. I only like to mix
enough epoxy for about 1/2 hours work anyway but I think it remains workable
for up to one hour depending on air temperature and how much you mix.
Mixing larger quantities decreases the time that it remains workable.
I cannot remember exactly how much I used but I think for the side skins it
was about 100ml each but don't quote me on that. I remember the bottom skin
used a large amount where it meets the engine compression brace as I needed
enough to cover the 3 1/2" x 31 1/2" piece of timber as well as the plywood.
I guess the long and short of it is to only mix enough epoxy that you can
use before it starts to go off.
Cheers.
