Based on the advice here about the Spraymax 2k clear, I took the plunge and bought all new carbon bits for my CSR. It is 17years old and on the original carbon which is, well, beyond saving to say the least. I keep them tidy with the Woodsilk etc to give them some gloss but it only lasts a couple of drives then they are back to faded and old looking. The new parts have no clearcoat on at all and are just finished in the resin from manufacture. I sanded them all down and applied th Spraymax. Then did a few passes with various grits of sandpaper and then a few passes with three polishing compounds. The way they came up compared to the "factory finish" was well worth the trouble. The Spraymax 2k is definitely my vote if the carbon you have is able to be saved.
