Found these and they are using epoxy resin with what they call a filler.

Difference is i'm using MAS epoxy resin with filler.
My question was really relating to how much is too much fairing. 1/16 to 1/32 inch is ok to fair? Moved forward with it and it seems fine. Will see when it's time to sand.
Hard to see in picutures and only spot that seems like it rippled just a little was the bottom hole at the top which I may have to touch up after the sanding.
