I use a product on the vinyl bed panels and plastic sail panels of my Avalanche that have a tendency to fade and "zebra" stripe called Refinish Restorer. Works great and last about a year on my bed panels which take a pretty harsh direct beating from the sun. It has a UV protectant in it to help repel damage. Brings the plastic back to new without leaving a greasy feel to it or making it too shiny. Only downside is it isn't cheap, but I can do about 30 Avy's with one can. I'm sure the dash boards on the bikes are made of about the same material.
Another vote for 303. I use it on anything plastic, leather and rubber......even the tires. Now before everyone goes all crazy on me for the tires, it does not "shine" like armor all and I make sure to wipe if off very well and it makes the tires look and feel brand new.
Gentlemen... Thank You... I have Enough Info Here to Play with and see What works best... Thanks to the "Painting" Tribe, But I Don't Think I want to Paint the Inner Fairing.... I'm Going to Start with Pledge and Then try 303 if Not Pleased.... Thanks Again Guys...
God Bless and Pass The Gas Can.... "Country Fried"
don't forget Protect-All. It works better than Pledge (and I like Pledge) and it has a UV protectent as well. Some walmarts have it or any place that has RV supplies.
P.S. it works really good on the back of the plastic GM mirrors too.
