Thinning epoxy greatly reduces its strength and its effectiveness as a
sealant.
It does get markedly thinner at warmer temperatures. If you want epoxy to
penetrate a crevice, warm the creviced material with heat lamps or whatever,
administer the epoxy, let it penetrate and top it up, then turn off the
heat.

A while back someone mentioned that you could thin epoxy with acetone.
I need to pour some into some cracks.I'm using System 3 epoxy. Thanks,
Jim
