I have a friend that owns a Corvette shop, anytime he sees a bra on a Corvette he descretly leaves a business card for the driver. He says using the bra he knows they will need a paint job soon. A bra can not be fit tight enough to avoid damaging the paint. Sooner or later it will get wet, stretch or something and the paint will suffer.
Seems like you're soliciting opinions on the subject and like most here I'm NOT in favor of the bra. Bras should only be taken off, never put on. [sm=lildevil.gif]
I used one on my bike for almost 3 yrs.Took it off only a couple of times to wax/ polish.But stayed on for most of the time. I would even wash the bike and leave the bra on. No problems, no scratches. The only reason I took it off is because a few the mettle clips on the elastic that goes behind the fairing came off.
