I'm just getting started in the detailing business and I'm just doing some jobs on the side for a little extra cash/hobby. I'm going to start off with a PC. Where is the cheapest place to get one and also what pads would you recommened getting? I have already ordered p21s wheel gel, adams claybar kit, m105,m205, megs apc, hyperdressing, gilmour foam gun. What other materials would you recommend getting?Thanks!
