Yes indeed, thanks guys.
My next move is going to be a trip to Ketts in Norwich, who are my go to for auto paint.
They have a good photo spectrometer, but importantly a couple of blokes there who know exactly how to use it.
I haven't put any fluid in my new 4 pad calipers yet, so I think I'll see if they can match a paint to the anodized caliper. The colour is cock on for what I want.
I'll be chancing ordinary base coat in a "warm" application, and it will be sandwiched between the VHT below and then coated with Satin VHT lacquer.
I actually used cellulose on my first Monster and it seemed to work okay on the outer covers.
