Paint Saga
I too needed avery small amount of silver frame paint. I tried BM dealership who said to look under the seat, this I did and found a code for the main colour which is not the frame, blind alley. I thought no probs will go to local automotive paint supplier and get them to mix a colour match, they do this either in 1Ltr cans or an aerosol, price much the same at approx £16. All i needed was a thimbleful however I thought surplus paint wont go wrong. Paint supplier was very knowledgeable and helpful and stated that any paint mixed would not be waterproof as it would need a an overcoating of clear sealer and that a direct colour match to the BM frame would be very hard to achieve. Price was escalating all the time with no garantee of a direct match. At his suggestion I settled for an aerosol can of alloy wheel paint which is close enough not to be noticed in my case. This is waterproof and cost £3.50.
He said that a lot of companies had pulled out of the bike paint market as there was no real volume in it, for example my Gs is black, however the only black on the bike is the front fairing anf the tank panel both of which can be supplied from BM in the correct colour in the event of major damage, so it is only leaving small repairs as their market.
