The door panels on my 07 Prius scratch very easily. Does anyone know of a product to cover the scratches?
I assume you mean the inside panels. Yes they do scratch easily. I just lived with mine on my 04 and have a couple on my 09. I have seen other posts where people tried different products with mixed results (mostly negative).
You can try these: For black trim, permanent Black Bumper & Cladding Coat for colored trim, non-permanent Black WOW Exterior Trim Restorer I've used the latter and it's good at dimming scratches, although it needs re-application a couple of times a year (depending on whether you regularly touch the surface or not).
