I use the thick rubber shelf lining found at the local Wally world. Cut a black piece slightly larger than the pillion. wipe the fender down good and place on the fender, then the seat. Works great.
Buy a cheap fender bib and cover it up. Mustang has some for $30. Want to go two up again remove the bib and voila.
I agree. A custom fender bib looks awesome and you won't have to mess around with taking that sticker off..... leaving it in place for some day you might want to add a pillion.
