I'm new to the forum, so if I put this thread in the wrong spot, feel free to move it. Thanks... I'd like to make a handful of hard plastic prop grenades for a photo shoot. I've used ezflo resin before with good results on other things, mostly very small items, but that stuff is relatively expensive for this purpose. (These props may never be used again) So, another idea I had was using fiberglass resin, which I can get in larger quantity at any hardware store. I'm not sure what the actual resin is (polyester etc?) But I wonder if I could use just the liquid resin, (plus hardener) without using any fiberglass mat or cloth. If this works, I'm sure there will be several projects in the future where I could use this more budget friendly option over more expensive plastics. Any thoughts or suggestions from the pros? Thanks a bunch for your consideration.
