If your cladding has NOT suffered from UV damage/color change etc., I recommend "303 Aerospace Protectant" by 3M. You can find it at some auto parts stores, and at most marine supply stores. I got turned on to this when I bought my Calfee Carbon Fiber bicycle frame - the owner/builder, Craig Calfee, recommends it to protect the frames he builds. (Sidebar - this is where ALL carbon fiber bicycle frames in North America are sent for repairs, regardless of who originally built them!). I'm lucky enough that my VX has been garage kept since new, so my cladding is in VG condition. I tried it a few weeks ago, and was flat out AMAZED at how easy it is to apply, how GREAT it makes the cladding look, and how long it lasts (so far)! Furthermore, it will protect your cladding from UV damage - that is this product's "claim to fame". I've found that you pretty much can't lose on ANY product with the 3M name...
