evercoat fibertech then rage gold. the fibertech is smc compatible and is structural. the duraglass can be used on smc but not for structural repairs. it can be used with regular fiberglass though. the duraglass tech sheet states to use smc repair fillers on smc for strength. i would rather use the fibertech due to the better adheasion properties to smc. i have used both and i like the fibertech better.

CAUTION: Blatant thread hijack ahead;The last time I worked on Corvettes, the "hot" sprayable filler was Evercoat Feather Fill. Which (if any) product mentioned here is closest to that product? Memory says this was a Polyester based material, as is the SMC (?) Thanks!

Have seen your work over the years.
You would have no trouble using epoxy and making your own filler tailored to your taste.
Buy the resin/activator for your cure time and add either cabosil or milled fibers to make a filler or even a panel adhesive.
Strongest and cheapest method without all the marketing hype.

i used that home depot resin crap and it seems to show a little over the years... i'm working on another forum members car with some molding ins and want to make sure we are 100% good.
when i worked on my 77, i used polyester resin, duraglass, and some evercoat feather stuff.

use epoxy resin on smc. the smc is poly based but has a mold release agent in it. this will cause the poly resin to have adheasion problems. you will have a lot less problem with epoxy resin in the future. spray the car with epoxy primer then put your filler on that. reseal it with epoxy primer and paint.

you may be better off laying a thin layer of glass with epoxy resin to gain the thickness back. then use filler where needed.

I use West systems epoxy for everything just as stated mix your own filler by adding what ever filler you prefer and tint to suit your needs.

SMC + Sheet Molding Compound. In the early days of fiberglass, parts were formed in a mold by hand using either a 'glass non woven matting and resin, or a woven cloth and resin "laid up" by a technician with a bucket of polyester, a paint brush or roller and some fiberglass... one layer at a time. Sometimes the mold was sprayed with gelcoat before the part was laid up, sometimes gelcoat was applied to the finished, trimmed part.
SMC is a "prepreg"; pre-impregnated; material which is layers of 'glass with resin pressed into sheets which are shaped with large heated molds to form the part. The resin is "heat cure" as opposed to "hardener cure" like the old stuff. I'm not sure if the gelcoat is on the sheet pre mold, or added after. And I hope my info is correct or the glass gods will strike me down for sure!
