It is interesting stuff. Today I used it on a Semroc Centurion F, on the fins (as a sealer and hardener) on the nosecone (ditto), and on the ends of the motor mount ring and body tube.
It tends to make fibers swell, so the nose cone shoulder had to be sanded down . . . which takes a lot of effort. OTOH just a few coats of filler are necessary; the stuff doesn't soak in.
I'd be curious how the hardener effects an assembled cardstock model or sub-assembly.
