Trying TO SAND MATTE BLACK PLASTIC . SO IF I SAND MATTE BLACK PLASTIC TILL ITS SMOOTH THEN AD POSHING PRODUCT WILL IT GET A HIGH GLOSSY LOOOK
Tooth paste on a rag may work. Have removed small scratches before.
Plastic is so hard that the matt finish you have now is not that rough. I don't think the sanding is necessary. They make plastic polishing compounds that might bring out some shine. Try that.
