i used primo before- theyre expensive- over 500$ to re powder 4 king coilover springs for my car. I also had them polish some beadlock wheels for my car a few years ago. i had asked him about getting those polished again when i got my springs done and the owner sat there for 5 minutes arguing with me that he doesnt do polishing and has never done polishing. I told him idk where you sent them or what happend but i dropped off the wheels here and picked them up a week later polished and the rings were coated. He got mad over that and i havent been back since.
Heard good things about specialized, kings and embee.
