Hiya. I personally did it before, but only for the reason that I was tinting my Raptor with the body color and because I was much more concerned with getting Raptor on my bc/cc than I was my bc/cc on my Raptor in case I didn't mask well. Wheel wells are a lot more awkward to paint with the tighter spaces and all that and I figure the risk of mistakes was greater when spraying the Raptor.
Also, please note that I've done one paint job in my life and this was it. I'm happy with how it all came out, but it definitely wasn't perfect.
