I've minorly involved in some composite repairs years ago, IIRC the resin used in FG repairs were pretty much the same with FC, maybe the ratio of catalyst/resin differs lil bit. I've also heard there's a company selling FC material somewhere at Jln Yap Kwan Seng KL, but can't remember was the exact name.
You could try to find "BIAM Chemical & Engineering" located in Taman Bukit Anggerik, Cheras. I know that they supply a lots of chemicals, epoxy, sealants etc and I think they should have some resin in stock..
