Quoted from Pinchroma:You shouldn't use compound on powder. Nothing with a granulation in it. Powder is not paint... Even a powder clear is still not something you can "compound out". Buff out yes with a wax and an orbital buffer but do NOT use a high setting or any type of cleaning wax. Use a finishing wax. It will take a while but you will be able to get the scratches out.
Remember, Powder is melted PLASTIC (Resin) and metallic charged fillers. It is NOT paint. You can't treat it as such
I had a few light scratches like those in the pic and used a piece of oak to rub them out.
Took awhile but the heat and friction polished them out.
