got one of calipers half finished with the paint - smooth yellow hammerite seems to work ok (off the car atleast lol) this is propably just common sense, but i think lots of thin coats of paint are better than a just a couple of thick coats. i havent done anything like this before so after id completely cleaned the calipers and carriers, i started slapping a thick layer on, and i was left tending to it like an icecream on a hot day - dribbles everywhere! lol ive just finished the second coat and its looking much much better - im thinking one or maybe two more coats and they'll be mutz nuts. i'll be putting up a readers ride thread in next few weeks and i'll be putting photos up of the process.
