Reflector: MGS Epoxy

[Ron Brown]

I have been using West Systems which is available at your local boat supply, 
in small quantities that  you don't have to worry about keeping for a long 
time.  It isn't cheap, but you don't have to pay hazardous materials 
shipping charges.

Be careful though, It sets much quicker and will exotherm in the mixing cup. 
I have also used it as filler when I painted this summer.  There are three 
different hardeners available - slow, medium, and fast setting.  The slow 
setting is still faster than the EZ-84.  The medium is fine for working in 
colder weather - i.e., you can use it below 70 degrees which is about the 
minimum for EZ-84 with out using local heat to set it off.
