The clear coat is on the tank only cuz it's metal. I spray it down w/ windex and then go over it w/ Plexus. It took me a lot of experimenting w/ different types of cleaners, waxes, polishes and I finally found a good combination. I usually wax once a month-clean with windex, mcguires tech wax, no plexus. If I use plexus after waxing it leaves a residue because of the wax. But that plexus works the bomb!! I also bought these $5.99 terry cloth also from mcguires (i got three of 'em). These are the best ones out there! I tried the clay bar but I think on plastic you have different results.
