I have a black synthetic stock that has scuff marks and would like to know if there is a way to clean up the marks. The stock is a smooth finish flat colored seventy dollar stock.
You might try a light bead blast with fine glass beads, but any sand paper, or abrasive pads, will leave tracks, that look worse than the dings in it. That is what synthetic stocks are for, to add character to that you don't want to add to a $1800.00 piece of exhibition grade wood.
