Beemaman from the DNA forum paints a lot of the DNA cars and is investing in a chrome spraying system. He won't be up and running for a few weeks yet but I spoke to him about getting the 250 mouth aperture chrome sprayed and he seemed to think around £150>£200. The cost is in the prep, the part has to be prepared and painted black to start with, the Finish has to be perfect before the chrome can be applied. I'm going to be sending him my panel as soon as he is up and running. He doesn't want to confirm the prices until he has finished a few.
Here is a link to show you the process, but of course it is really magic.
Now all we need is Chris to sneak round to Smash's and do a splash mould of his bumpers!
