I was wondering what is the proper way of sanding fairings that are not on the bike. Do you sand it by hand or with a power sander? Also what grit of sandpaper would you use to get rid of the paint and what grit to use to smooth it out before and after the primer. When I got hit by the bear it cracked a couple fairings and I also just got a solo seat that I need to paint to match my bike. I've done bodywork on cars before but not a bike.
