24k mi. on V&H Bigshot Duals.Still look like new,easy to keep clean.As far as touching up scratches.haven't had to yet.I've got a small one under the left saddle bag,which you can't see.I'd probably mask off the scratch and touch up with high temp. paint.Larger ones would probably have to be recoated.
Really nice looking scooter you have. I recently painted my 2-1 Python exhaust with VHT ceramic paint and it looks great and wears well. NO complaints.
