After washing my GTP I have come across a problem that I have not had before. The area on the rear plastic bumper around both tailpipe outlets has a film which feels like fine grit sandpaper. I'm assuming it's from the exaust.
Any ideas on product & procedure to use to remove this film ? I tried scratching the film with my fingernail but it felt like the gritty film was baked onto the paint surface.
