yes it is, but most use C/A.
I don't build anylonger, nor have I competed since 2007 or 2008 can't
Most all high performance models are molded or glass/carbon/kevlar over
foam. Mine were molded carbon fiber so they were used epoxy.
I actually think that ambroid is better than C/A.. while C/A is fast
cure, ambroid is not as brittle. But only some of the old timers build
with it. And maybe some indoor guys, but I'm not sure.

And I agree with that. I usually had ear muffs, so when I was right beside
a running machine, they would be on, but then when I was trying to
communicate with a student, they would be slid off, at least one ear. A
mistake on a running machine can still be heard, clearly, if you know what
you are trying to hear.
