I know its that harbor Freight guy again! I do a lot of plastic stuff. The sets have nylon, brass, and steel bristles. The nylon for shiny plastic but on some textured surfaces the brass works to. Russ
And no I don't work for HF, just a cheap guy thats uses their stuff.
Just watch out for the brass brush discoloring light material. I guess it leaves a petina color. I used it to get the fuzzies off of a piece that was to be painted.
