Tough-Cast 75D Black

great product I use for model tires and I am looking for other parts

This stuff is great....very tuff! Will be my go to for mid-size prototype projects

Tried the new 75D Black, Works Great!

Product seems good, works well, but isn't "black" as the name implies. The 65D Black is like night. This stuff is more like charcoal gray and a little translucent. The hardener (Part A) was lumpy at first pour, almost like it partly coagulated or had clear boba in it. A good shake and that resolved. I am familiar from the regular 75D that the resin itself (part B) would collected small solids at the bottom of a bottle that was stored for a bit and would require shaking. No idea if that's the same case here BUT I shook the black anyway, then poured the weight I needed and let is sit for a few minutes before adding Part A in. That's my top tip. The minus one star is for the non-black "blackness." Otherwise, product works well.
