Yesterday I collected some touch up paint for my new Cloud Blue. I hope that I won't need to use it but I am glad to get some - just in case.
Brompton used to produce and sell touch up paint but no longer do so. It is now a case of looking up the RAL number and finding somewhere that sells that particular number.
I have to say that this particular paint is a really good match. I tested out tiny amount on a part of the frame that you'd never look at and it was perfect. Worth buying a bottle if you can find it.
Stay safe out there people!
