I think this suit is going to be awesome
That Bondo thing is strange though. Did you maybe have an air bubble in there or something? (And what did you say where the heat came from...?)
The Rondo (not Bondo) goes on quite smooth, so no air bubbles. The heat source was a 500 watt work lamp, and that spot was sitting right in front of the lamp.
Also, that reminds me. I've been Rondoing out in the garage with my hot box, and it's been so cold that the Rondo is freezing as I put it on, and then it melts in the hot box. It makes for some interesting flows once it melts and then cures.
