So I am cleaning my old car up so I can sell it and there is this stuff on the rear window molding that I cannot get off.

Here are some pictures any ideas?





It looks like it is on top of the molding and not down in the finish.

 

Looks like it needs to be sanded and repainted...

 

Tough to tell from your picture, but it looks like that IS down in the finish.

Look like it's damaged from the sun.

 

Looks like rust.

 

looks like oxidation. any pics from further away? might have to repaint

 

I don't have any pictures from far away sorry, but that molding is not painted. That molding is a really hard rubber, I was able to get a little of it off with some 409 and a tooth brush however that will take for ever. I didn't know if anyone had a product that would work better.

 

try some clay bar.

should come off.

 

more pictures would help... i would suggest washing it well, then claying it (this will remove as much of the contaminants as possible, leaving a clean surface for the next step)... mother's 'back-to-black' or cg's 'fade 2 black' could work, but my understanding is that they tends to wear off after a few months... and if you want to spend the money, leatherique makes a black dye that would definitely work more permanently (but like most of leatherique's things, it's pricey)...
