[Paddlewise] Epoxy questions

I have some Titan brand marine epoxy with the fast hardener.  Even in a 
60 degree room, I find that if I mix much more than about 3/4 ounce, 
after a few minutes, the stuff goes into exothermic mode, producing a 
chain reaction where it starts to bubble and almost immediately harden.  
I realize I can use a larger container to help dissipate the heat, but 
it ends up wasting a fair amount by being so spread out.  I've heard 
that if you ice your mixing container, the reaction can be avoided at 
the expense of dealing with a thicker mix.  Are there any other 
disadvantages to doing this?  My thought was to ice it until it's 
applied, then move the project (I'm making fiberglass covered J-cradles 
for my roof rack) to a warmer room to cure.

And as long as we're on the subject, the best deal I've found for 
no-blush marine epoxy is through http://www.epoxyproducts.com (seems 
like a reputable dealer, but in serious need of a skilled web designer), 
where in small quantities, you can get 28 ounces for US$12.50 or 6 
quarts for $69.  Anyone know of a better source?  I tried buying it 
locally, but have had a surprisingly hard time locating it (other than 
the quite expensive West Systems brand from a marine store).

Thanks for any info.
