I used zip strip from the local Ace hardware store and it worked pretty good. It took more than one coat but I did it in the dead of winter in the garage and it recomends 70* or higher air temp.
I think it was about 40* when I did mine. Be sure that's what you want to do though, when I did mine they sure looked great but they take a lot of maint. to keep them that way. You either have to coat them clear again after your done or take them off during the winter. I got caught out on a light snow day and the solution they sprayed on the roadway really started to mess them up. I had to take them off the car and re-polish them all over again!!
