Not happening. Pledge, or any other spray on wax, contains oils, which look really nice and shiny at first, but will attract dust and dirt. Or rather, dust and dirt will stick to the oils in the wax. The dirt and dust is abrasive, when you wipe the dust and dirt off, you are scratching the clear coat. It might take awhile, but eventually it will dull the finish on your bike. If you really want to protect the clear coat finish on your bike, sponge it off with warm water and some dish soap first(easy with the hose or any high pressure water source), use something like Super Glaze, from the Wax shop. It's not cheap, but it contains no abrasives, dries very quickly, and leaves no oily residue, so there's very little for dirt to stick to. When you use oily, spray-on waxes, it's like adding a temporary coat of clear coat. It'll look good for a little bit, but over time all the abrasives (dirt) that you wipe off will begin to dull the finish just like you used a piece of sandpaper on it. Take it from someone who has detailed a lot of Harleys.
