anyone have experience with this? i’m not sure what the hardness rating is, but this is the first time i’ve tried messing with urethanes for making molds.
this stuff just seems like fiberglass resin with the viscosity of epoxy. it’s sitting out right now curing on my part that i’m molding from, but because of the viscosity the piece drips so much so i’m going to have to build up a lot of layers. should the urethane cast kits be like this? should’ve just done a fiberglass mold in the first place.
anyone have tips or tricks to thicken up this product? i’ve been thinking of mixing in twill with the urethane (like a milkshake) and applying that to the part i’m molding off of.
