I do custom paint painted helmets and have done a bunch of Harleys and various other brands.
I just put an M3 front end on recently.
I use House of Kolor exclusivly on the custom stuff, and I have been a big fan of Dupont chromabase and Chromaclear. it's very user friendly unlike PPG where you have to mix alot of things to the paint and clears to be ready to spray.
Dupont you just mix paint with basemaker in a 1 to 1 ratio. the clear is just as easy with a 4 to 1 ratio and you can also add a touch of reducer in the final topcoats for flow out.
