I have been washing, claying, hand waxing vehicles on the side in my area for years. Recently I have more and more people want me to get into correction work and I would also like to do the same on my own vehicle as well. Since there is no one in my area that is reputable I figured it wouldn't be a bad Idea to learn the correction process. My question is do I start out with a pc 7424xp or griots garage, or should I go ahead and get a rupes or flex? I'd hate to get pc/gg and end up wanting to upgrade in a year or so, but I don't want to get something that is too far out of my league either.
