US composites, was cheaper than West System for resin and other things. I have about $300ish invested. Ordered mold release wax and a gallon of PVA, a gallon of resin with hardener, pumps for them, and 5 yards of 50” wide 2x2 5.5 ounce fabric that was on clearance. The total was $265? $50 for a 4’x8’ pink rigid insulation foam. Have 5 feet left and 3/4 of the resin. Wasn’t fun chiseling it out, but would hate to have to deal with the melted leftovers if I dissolved it. Going to make front bumper brackets using molds and vacuum bagging. Just want them to hold the bumper on safely. Figure the steel ones are 3/8”? Buy a roll of 2” “tape” should be able to get about 20 layers per bracket. Probably stronger than the steel! The carbon fiber was probably on clearance because there is a very subtle wave in it as the light catches it that if you were going for the shiny carbon look, might make you unhappy.
