LedHed, I attempted one mold with the RTV. Results were not good. LOL. Once I have a little free time, I will try for round 2. I have a package headed your way in the next week or so. I am throwing in a few surprises.
Overkill, Tell me more about the fiberglass resin. I like the part about being "more Soupy". Have you made a mold only using the fiberglass resin?
Husky, Your tutorial is the reason I tried the bondo. Thank you for putting it together.
