After installing my new Ducati Performance Air runner, I couldn't help but notice how crappy the the fender, airbox, and other runner looked! Any ideas for faded carbon fiber? Thanks in advance!

Re: Refinishing faded carbon fiber (J.U.996SPS)

Carbon Fiber Care

Carbon fiber composites get brittle and faded from oxidation caused by the sun's UV rays. The UV discoloration is a combination of both the carbon and the resin color changes, so in order for carbon fiber to retain its appearance, it has to be clear-coated by either the manufacturer, or you, prior to installation. If it's shiny direct from the manufacturer, it's probably been clear coated. But check first before buying.

Since exhaust cans operate at elevated temperatures, this will accelerate this oxidation and also quickly drive off any wax, oil or silicone coatings you apply to try to keep them shiny. Automotive paint clear coats are very resistant to UV discoloration and oxidation, so the best solution, even for carbon exhaust cans, is to spray them before installation.

To restore carbon fiber that has started to fade, wash it with soap and water, rinse it with paint thinner, and let dry. Apply three or four coats of clear acrylic enamel or lacquer, the first coat just misted on. Lightly sand with 600 wet between coats. The black won't be as deep in any faded areas, but pretty-close.

Clear-coating carbon fiber can be time consuming because of the pinholes in the material. To keep it lightweight, it shouldn't contain any more resin than necessary. Nevertheless, some manufacturers focus more on the cosmetic aspect, so their products are dense with resin and very shiny.

Unless your carbon fiber has been clear-coated, keep Windex or harsh oxygenated cleaners like 409 or S-100 or Oxyclean away from it. They turn raw carbon fiber mottled white and milky-looking. In some instances this milky stain can be removed with denatured alcohol before clear-coating.

Re: Refinishing faded carbon fiber (Shazaam!)

My DP front fender (Monster 900ies 2000) has become yellow...Is it due to a bad quality resin? How can I remove this ugly yellow reflect?

Re: Refinishing faded carbon fiber (vfr31)

can't help there VFR...but sounds like super fine sanding and respraying clear coat...and hopefully the original C/F resin used was of the more UV resistant type or you may have what you have.

Does anyone know if QB Ducati carbon parts are outsourced and brought back from more than one provider? Just wondering about the front vented fender and its C/F make up....it surely is all C/F not with the cheap FG undershell but wondered about their wet layup vs. autoclave......and C>F binder used.
