So I was just in the shop/basement, and was setting up some new acrylic wheels in a double stack, there was quite a bit of difference between the the two wheels in the stack so I went to work truing them up. My god! The amount of fluff that went a flying was crazy, it doesn't just fall to the ground it keeps floating till it sticks to something, which just so happened to be all my kit for work (didn't want to clean it up with my work bench right there looking at me ). Pain in the ass to clean that fluff up, I just ended up rewashing it all. So I don't know how many of you guys use that type of wheel, or have thought about it, but as a word of warning do it outside or somewhere it won't stick to everything.
