I have a small scratch (1"x2") at the left corner of my front bumper while another car touched it parking his car, and he drove away. The original paint (Irridiumsilver) has completely gone and the black of the "plastic" can now be seen. I tried to repair it with an original small paint can with small brush in that I bought at MB but now you see the dammage even more. When I was in Florida early this year I saw in a car periodical that in the States exist some "repair pen" ?? Can anyone give me the website of this company ? Thks in advance.

 

The way vehicle's clear coating + sprayed paint reflecting light makes scratches and brushed-in touch-up paint stand out. Therefore, MB original paint alone can not hide this 1'x2" area. Try to polish and give it a few clear coats see if it would blend in.

For small line scratches, here are a few paint pen web sites:
fix-it , nicks and dings

 

just leave it and live with it, this comes with car ownership

 

The 2 part touch up paint kit from MB includes the base color and clear coat... if used right, it should be okay to great looking. It does take a little skill.

 

i would talk your service department as they always have a guy there that can do some on the side painting and maybe he can fix it for you.

 

If you brushed the paint on to a 1" x 2" area, you are probably seeing brush strokes. Spray would have been better...

I hesitate to offer the following advice as it could make matters far worse, and would strongly recommend a body shop fix it for you (as you were asking about). Since this is a new, expensive car it doesn't make sense to get your first experience at body work on it.

But here goes:

You could try sanding the brushed area down. Start with a fine grit sandpaper, maybe 400 - 600 (at 600 you might want to use wet paper), and try to blend out the brush marks. Blend the new paint to the old. Do not sand off the "good" paint around the affected area. Start with the finer grit paper and if you need oomph more go coarser.

Once you have the brush marks mostly sanded off, switch to 600 -1200 grit wet paper.

You could also use rubbing compound, (I think most of these products are like in the 800 - 1000 range).

Then go to 2000 grit paper, or use polishing compound.

Clear coat and re-sand with the ultra fine stuff, or just use polishing compound.

Use glaze or wax.

This is better left to professionals or those who can gain experience working on older cars that are not very valuable...

 

Thanks guys for all the usefull answers.
Does someone has experience with : Dr Colorchip from Lakepark, FL ?
