Best product for oxidation removal?

I got fed up looking at the ugly spoiler that came on my car, so this morning I removed it and sealed the holes with a screw/rubber washer/nut assembly. (This is, of course, a temporary solution until I have a bit more money available to me, at which point the holes will be filled and the trunklid repainted).



I washed the trunk and applied Klasse AIO and SG. The AIO certainly helped with the oxidation present, but there's still plenty left that I'd like to get rid of. Here's a picture of what I'm talking about:

What should I use to get this grime off?
 
Well, your next step would be to graduate up to something a little stronger. Maybe Meguiar's #9 or even 3M SMR. Do you have a machine availible to you to help out with this? I'm suprised that the AIO didn't get it all off.



The bad news is that you are going to have to SG again of course. Anything that is going to take off the marks on your bumper is sure to take off the SG on top of the marks. No biggie though.
 
I am going to guess and say that is a e36 BMW M3.

The clear lights and color make me think M3.

AM I RIGHT AM I RIGHT?!?!?!

:)
 
Right you are! It's a '96 M3 Coupe in Estoril Blue. I took the spoiler off because I just didn't like it. The previous owner put it on, and it came on the car when I bought it a month ago. My dislike of the spoiler reached a head this morning, so off it came. I also realized that I could do it without actually having the money for a fill/repaint. :)



As far as the AIO not getting it off, it's actually not just black grime as it appears. It's full-blown oxidation, best I can tell, which is why I'd guess the AIO isn't cutting it. Seems like something abrasive is in order, here. What is the full name for 3M SMR (I'm not on the up and up as far as most abbreviations)? No, unfortunately, I don't have a machine.



Either way, I'm not too worried since the trunk will get a repaint within a couple months; I just want it looking better in the meantime.



Here are a couple better pictures of the oxidation:

I would change those metal screws if I were you. They can get surface rust around the edges of the screw and transfer that to the paint. If you can find plastic screws big enough to hide the holes I would use them.
 
Still, AIO has always done wonders for me and oxidation.







Those results are with AIO all by itself. It took 2 or 3 applications, but it got it off pretty good I'd say.
 
Don't worry -- everything I used is stainless steel. :)

Hmmm, well, I'm going to get out there with a clay bar and some AIO and see if I can't fix this, then. Results shortly!

CLAYBAR!! :doh Great idea. Why didn't I think of that? lol Good luck. :up
 
Looks like dirt to me. Oxidation is usually chalky and whitish, not black... The clay might do the trick. :up



I'm kinda curious about the spoiler. Was it a OEM style spoiler, or some clearly aftermarket ricey spoiler? I kinda like the OEM ones personally, and would put that on instead.
 
Does it feel rough at all? It could be dirt or maybe some kind of paint failure.



Jngrbrdman, great before and after pics :xyxthumbs

I had a rubber stain on my Dad's car and I first went to Wallmart and got 3M Adhesive, Tar and Wax remover (or something similar) to take off all of the upper coats.



Clay Bar is a great idea to try.



Then get 3M Cleaner Wax Medium Oxidation remover, and rub and rub and rub and rub, It does come off.

I agree with mrdetailer... wash, then spray some adhesive remover (like 3M Bug and Tar or Goo Gone), then clay, then follow up with 3M MOR, then re-Klasse...



3M MOR is my go-to-product for oxidation and hard water stains... :)
