One thing I might suggest is that to avoid color match problems from can to can, buy all your paint at one time and put all the cans together into one, then shake or stir it really well so you get one big batch that is a combination off all the slightly different mixes. Paint stores are generally pretty much dead on, but slight variances do occur.

Jay (Hotrodpaint) will probably be able to offer some thoughts on this subject.
