I just learned today, Marble will also sell paint only for anything he’s developed paint codes. About $300.

Hi Pete - I hope you are well. I’ve hopefully found a front mudguard for my bike in better shape than the one currently on the bike. With your colour match for the silver, how did you get the match? Looking at colour swatches? (Physical or screen?) or did you take your mudguard somewhere to get matched? Do they do it by eye or have a ‘machine’ to do it? Thanks, Phil

Phil, I went to Paint Services - Reading.
Address is Unit 8, Gresham Way Industrial Estate, Gresham Way, Reading RG30 6AW.
Have a look at #140 on this thread it has a photo of the paint details.

Does anyone have a good replacement silver paint for the front fender for a 1973 RT3?  What brand of clear coat is best?

Both answers in previous posts in this thread, but to save you time and spend mine;

Duplicolor DE1615 for the fender, spraymax 2k matte clear for fenders and spraymax 2k gloss clear for tanks/headlights.
