Hoodlum: Fiberglass resin works fairly well for molds if your looking for an economical material. I have used alumilite (I think that’s what it’s called). The alumilite was much better quality finished product, and I have a gallon of body filler that I am going to try to make some molds out of: it’s also a very inexpensive option you can try.

Liftbite56: I agree, proper tools and safety equipment is absolutly a REQUIREMENT for 350 degree molten plastics! I’m not sure how popular it is to insulate injectors but it made a HUGE difference with my methods. Along with keeping the injector and tip on a hot plate while prepping the plastic. I always have too many sets of gloves on the bench so I NEVER forget to wear them either.

I would like to see a better quality molding material at a more reasonable price. Alumilite is super expensive but the quality is fantastic compared to those I have made from resin and I done expect a lot from the bondo body filler... there is a lot of science involved in making a mold that works and to be honest: that science is beyond me! Lol. I’ll keep working on new molds and hope to be able to offer some more advice in the future-

enjoy guys and be safe! No lure is worth a burn with this stuff-
