Assuming it's RCS or Alclad chrome, I always go with two light coats of waterbased black before any other colours. I've had some slight issues with chrome pins lifting when removing surrounding mask if I get a bit carried away, but never with it flaking in a crash.
TBH chrome gives me fits all round. Love the effect, hat working with it lol.
Julian, I know where your coming from mate. Ian and I were chatting about it on Sunday at TORCH. I'm getting back into painting ATM, after being out for a couple of years to concentrate on racing. Now I'm racing a bit less, and have more time in the evening (electrics take up so much less time than nitro

) I'm looking to do more spraying. Constantly having to be 'on form' and producing the goods in terms of design and spraying is a lot more pressure than anyone who's never done it can imagine.
