I am not a happy camper today. I spent a bunch of money to have GC50 sent to the US because its the only thing that will work according to Easy Composites.

I followed every direction perfectly and soon as i cut the part, it start to chip up immediately.

I got the mixing portions right, i bought a spray gun. Laid it on a bit thinker, maybe 0.5mil or 0.6 mill, but should not of been a problem since some people brush it on heavier.
i let it stand for about 10 hours, well after the 2-3 cure time and well within the 24hour max out period. i did resin in fusion. i let the resin and the gc50 cure for 3 days. first cut, darn near instantly started to chip up and de-laminate. i used a cutoff wheel and actually moved downt eh part slow and moved fast to see if it was heat or speed, still happened no matter what.

i am at a loss guys. this product was supposed to be aon a show car tomorrow and i completely blew it because of this issue. i really dont understand.

here are a few pictures.

MEKP varies MASSIVELY. I've actually got 5 different brands in stock because each gives me different advantages, eg. longer or shorter pot lives, higher final cures, lower porosity, etc.

Matt,

Yes, thanks Frank, that sounds like a great way to go; it's all about finding what we can rule out and then seeing what's left at the end. Warren and I will monitor this thread and respond once you've had a chance to do some tests with a different epoxy.
