Im guessing that the surface isnt completely clean, so it may not adhere to the plastic. I would say give the cladding a really goos cleaning before applying any more. If you want some REALLY great stuff for your cladding tray a product called Refinish Restorer. I applied it to my cladding back in January and its just starting to fade. Doesnt wash away with rain. Mkaes the cladding look BRAND new. Awesome product. Not cheap though, about 50 bucks a can. If you plan to keep your Vibe for a while & keep the cladding freash it really is the only way to go outside of painting LOL. Do a search in here and there is a thread dedicated to it.
