What is the best way to fix scratches on a plastic bumper instead of replacing the whole thing?

I hit my rear bumper and don't know the best way to get rid of the scratches on it. My car is a 2005 Jetta in which it can get expensive to replace the entire plastic bumper. It costs around $200. How much do those plastic scratch removers cost? How do you use them? I don't have any holes in my bumper, just a lot of scraps.|||If you can get your fingernail into one of the scratches as you run your nail across the surface, the scratches are too deep too buff or polish out. It must be re-painted. If the scratches are through the paint and primer, and all the way down into the plastic, you need to fill those scratches with a special plastic repair material, and all the appropriate adhesion promoters, since the bumper is made of a plastic called TPO. Getting paint and filler to stick to TPO is like trying to get something to hold onto teflon. It will flake right offf at the next slightest impact. To remove the bumper, fix the scratches, paint the bumper and reinstall it will cost about 8 hrs labor and $100 in materials at a real body shop. You are looking at about $400-500. If you have to replace the bumper, add a couple hundred more. Personally, there is a reason they call them bumpers. Just touch it up. As soon as you fix it, somebody is gonna hit it again. Don't waste the money unless it's cracked or really ugly.|||Well, the best way to make scratches disappear on plastic is by using wax !! You can also try 'heat moulding' so that the surrounding plastic can be folded over the scratched area, giving a good appearance. However, please don't try this yourself, go to a trained mechanic, who will fix the problem at a cheaper rate !!


Good Luck !!|||2000 grits wet sandpaper with a electric sander will be the best to remove straches on plastic if they are not deeper than clear coat .
