RickOKC did some good testing of products on the cladding, one was 303, here's his post with the findings (post #19 above also listed it).
Some of us think if you wipe the cladding dry as directed, AND let the 303 treated cladding sit overnight, less dust will be attracted to it, as it seems to dry a bit more and stick less. (303 will NOT be sticky at any point on your cladding.)

No disassembly of headlight required, just put double to triple tape around the edges so you don't buff right through it and hit your paint. If you do wet sanding, the water mixture running down always caused my tape to want to come undone, but keep reapplying tape if you have too....it's too easy to have the drill jump and hit the paint. I bought the 3" wide painter's tape. I actually think DUCT tape would be better since it's stickier and thicker.
