The FAQ on my website is the best place to start (scroll down a bit past the Contact stuff). It tells you everything I need to know to give you a proper estimate rather than just a guess.
There's a whole segment devoted to MP valve covers. (I do know the bodywork has to be on point to pull that wet black off to reflect like those do, but it's a crucial part of my job on everything.) Please don't feel obligated to choose a previous color scheme either -- gun cleaning time costs the same regardless of the color I'm getting ready to put in it.
Thanks for asking, and for looking!!
