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.

Definitely a strange one, hopefully one of the EC staff will be along soon and has some insight. I had a similar issue once with an epoxy infused carbon/fibreglass part where the fibreglass delaminated from the carbon like it was peel ply. Never really found a definitive explanation, it was a part I had made before and a part I have made since and never had the problem reoccur. 

Feel your pain about binning so much product, it's really the downside of using an in-mould coating vs post-mould clear coating. I've binned plenty of products that would have been fine if they didn't have a coating. 

Not that GC50 isn't a good product, but it's far from the only product that would work. Being in the US, you could get Duratec Sunshield very easily I'm sure. Scott Bader Crystic Glosscoat is another one, though not sure on availability in the States. Just for future knowledge.
