On my matte gray F800GS, my knees are wearing the paint away on the side panels. I was wondering if anyone has tried anything like this: http://www.wunderlichamerica.com/mm5/merchant.mvc?Screen=PROD&Store_Code=WA&Product_Code=1250007&Category_Code=F800GS-X or http://www.motorradzubehoer-hornig.de/en/025_02758__BMW_F_650_GS_F_800_GS__Paint_protection.html# It is nothing major yet, but the inside of the knees on my pants is turning gray, and the paint has glossy 'spots' on each side now. Do these things wreck the paint if you take them off? Anyone have a similar problem? Better ideas or solutions? Recommendations?
