Getting ready to build engine /fuselage crutches . Dug out my Zap brand 30min epoxy and the resin part is nearly solid is it ok to heat it up in warm water to get it back into a viscus state?Then mix as per normal and use it or is it no good once it gets to this nearly solid state in the container? I keep the house at about 63* to save $, hope I haven't killed a nearly new bottle of epoxy.

Gordon,
I heat up my epoxy all the time. Some times in water, other times with the head gun. Works perfectly. Also when I apply it, I heat it up to cause it to flow better.
Cheers, Jerry

It will probably be fine once you warm it up, but you definitely want it to cure at a normal or slightly elevated temperature, 63 won't cut it.

OK , I will put an old 60watt incandescent light I have on it and up my SMUD bill a bit. Thanks for the advice , I have most of the stuff cut out and in kit form. Time to start gluing the bits and pieces together.

Put the bottles in hot water for a while, that way you won't overheat them. When gluing, it's really worth the trouble to let it cure in elevated temperature (50..70C), especially with faster epoxies & hardwood. That way you'll end up with nearly 50% stronger seam.
