Around these parts we have outfits that install a durable layer of plastic film to put on the front areas of vehicles, knowns as "clear bra." This film is to help minimize rock chips, etc. I went down to the local clear bra store and they gave me all sorts of trim pieces and even told me how to apply it using soapy water so it can be perfectly slid into position. On all of my bikes I've installed this material wherever things might rub together. It's a great material, nearly ivisable, and totally free. It can be removed by using a hair dryer set to the hot position. There are also other products out there, but this stuff is great (and for me, free). Check it out!
