tuto993

Hello All. Yet anoher issue as I try to bring my recently acquired 993 up to date.

I this stubborn staining, if you will, in the rear part of the wheel arch that woukd like to clean. It is like the previous owner drive over a construction site and "dirty water" was present, perhaps with some kind of glue or paint in it...

it is only present at the rear righ wheel arch on the rear bumper portion of the arch.

I've tried Meguiar's Mirror Glaze professional fine cut cleaner (#2) followed by medium cut cleaner (#1) with not much improvement.

Does anyone out there have a DIY suggestion?
Thanks!

Try Goo Gone. Not Goof Off, but Goo Gone. it may take a few applications, but it won't burn through the paint.

This stuff?

May simply be chips or tears in the clear-coat. If this is the case spot wet sanding it lightly with 2000 sandpaper, buff it out and see if it helps. If it is through the clear-coat you could test over-spraying a small spot with spray gloss Minwax urethane lacquer sold near the fine wood finishing products at a Home Depot store. This seems to minimize the perception of chips, gouges and other irregularities in damaged clear coat.

I replaced the door sill strips on my C4S with the stainless $$$$ ones and used an "eraser" to remove the adhesive residue. Body shops sometimes use it to remove applied decorations on painted surfaces. Didn't seem to harm the paint but others may chime in with comments........ assuming the debris is "on" the paint and not "in" it......just say'n

Yes. There are several varieties with varying strengths and citrus additives. Any will do the trick.

I have a similar thread going about removing cosmoline. Some have recommended xylene. I used it to remove some adhesive residue when I removed the Carrera logo from my rear deck and it did melt it right off.

Apologize for the loud the background music...

i made a few passes with Goo Gone (not the automotive version, mind you. Just happened to have some in the pantry).

decided to use an exacto knife to carefully scrape the material (whatever it is)...

And this is what was left... not bad for DIY government work.

Nice work. A plastic putty blade knife or a credit card may be safer than than a scalpel, but you did darn good there. You can soak it overnight with the goo gone and have another go at it in the morning. I will say, that Xylene really works if you need to take it to the next level.

^ Sounds like this may work for the stone guards on the fenders. I know there are threads out there for that removal process. I need to look them up because I think I am going to swap mine out soon.

Goof off is what I used to remove the adhesive. I have an old tin of it that worked great and its active ingredient is Xylene.

I ran out and picked up a new can. Looks different and its ingredient is Acetone and Xylene.

Have not tried it yet on my cosmoline wheel wells... Not looking forward to that job.

In revisiting the post the crud may be mineral deposits from the construction site where CLR or some other scale removal wash would release the minerals from the paint??

i try to stay away from Goof Off. If Goo Gone doesn't work, try Xylene. Goof Off has xylene combined with acetone, as noted. The acetone can burn right though the paint if you rub too hard. The Xylene won't do this in my experience.

samurai_k

Thanks. I had an old tin of Goof off shaped similar to a zippo lighter fluid container which only has Xylene. Did some research and it looks like they changed the formulation. Going to return the new one now and pickup up Xylene...
