I have read threads here about this stuff many times and it seems that it is all that some folks use. The particular brand I had was Weldbond and I decided to use it on the fin can/motor mount of an Applewhite saucer just to give it a go.
I tacked the fins and launch lug on with thick CA glue and let it harden, then filleted with the carpenter's glue. First of all, I am glad I was not in a hurry, as it took hours for each set of fillets to dry. When they did dry, it seemed that the glue was mostly liquid, because all that was left was a thin yellow skin. It will take at least two applications to get good fillets. To actually glue fins on with this stuff, I would have had to hold them in place for twenty or thirty minutes, minimum.
I will go back to gel epoxy for filets. I have never had one fail, it is set in 5 minutes, and one application is all that is necessary. I can mix enough for two sets of fins and rotate or hold the rocket in any position to work on it without having the stuff run everywhere. Smooth and wipe excess with alcohol, and it it is done.
I do and will continue to sometimes use yellow glue for certain construction projects, like motor mounts.
