PC won't stick to primer. If you have a PC shop right down the road and it's warm with low humidity, you can blast yourself.
Honestly unless you have a massive compressor, good size gun and a half/whole day to kill, it honestly isn't worth it. They may take off 60-100$ depending on the shop you use.
Be your best bet to call around for local shops, but I can't stand open blasting. Silica sand causes cancer, aluminum oxide is about 1$ per pound and it gets everywhere. A smaller compressor may work but I've blown up 2 of them that way.........
All our government does is distract us while they steal from us, misspend our tax $ and ruin our country
