    How to repair scratches on a front lip?

    Let me preface by saying I'm an asshat...

    My wife and I went to DC yesterday to enjoy some fireworks so we parked in her work garage since she has a parking pass on M street in Georgetown. She warned me not to go up one of the side streets but I thought I knew better...bad move. That was even after she told me she witnessed that street injure many a Porsche. Luckily the bumper has some give so I didn't leave any bits behind but scraped up my STI front lip. I was expecting much worse with the noise it made but ended up with this:





    Any ideas how to fix this? Maybe some fine grit sandpaper and do some wet sanding? Seems like it would work well enough to hide the damage with the black plastic.

    Lesson learned: Listen to your wife/girlfriend once in a while. (maybe...)

    It wasn't painted--just the flat black plastic. I'd prefer not to paint it because...well...it will be painted and show scratches and chips more easily. I'm curious if I could get away with sanding and polishing it without looking like ****. Any thoughts?

    Honestly I've painted both of my front lips satin black and my scratches looked just the same as the ones you have.

    Im not sure about sanding and polishing without paint

    I guess maybe try it and see what happens

    Worst case scenario: paint it. Lol

    use a black sharpie and fill the spots

    hard wax will not work its not painted... you can use spray wax and kinda scrub it to get some blemished out maybee but to be honest just touch it up with something black you probably wont be able to tell

    if you sand it its going to look worse if you dont paint it after sanding

    Painting isn't an option right now since I don't have a garage. But yeah, I like your idea--give it a shot and default to painting if sanding/polishing doesn't work. I'll probably try sanding the underside as a test and if it fails I'll look at the scratches for a few months.

    The problem is matching the color. My luck it would be more noticeable than the scratches.

    Isn't that plastic black throughout? Can't you just buff it out?

    Yep, it is plastic with no paint. That was really my question--how will it turn out if I do some wet sanding with really fine grit and polishing? I've never done anything like at on plastic so I was curious if anyone has and if so, how to do it.

    This is my fallback plan. I have DGM paint in a can that I used for the grill and chrome trunk piece. My only concern is how it will hold up over time. The way the front end of the car is chipped with factory paint I can only assume it will be worse with rattle can paint.

    I don't picture this being easy to do right and match the appearance of the rest of the lip. You may not have the scratches any more, but you could end up with a larger area of slightly differing finish. The entire lip may be molded from the same plastic all the way through, but the outside probably has some type of coating or treatment. If you do try this I'd find a small out of the way area to thoroughly test it on first.
