My car lives in a car port directly under the large drain pipes that carry water and sewage down to the main drain at the street. The pipes leaked around the joints and now I have crud on the roof of the Z. I assume it's sewage... kinda reddish-brown in color.

I wet it down and tried gently rubbing, to see if it would come loose, but it didn't. It's definitely above the paint cuz you can feel it raised above the surface. But it's got a firm grip on the paint.

Any suggestions? As you can imagine I'm concerned that I not scratch or remove any of the paint in the process of getting the crud off.

TIA for any words of wisdom!

 

The first thing to try is a claybar. It's great for removing contaminants from the surface of your paint.

You can also try mineral spirits/WD40 to see if it dissolves the solids.

If all that fails, there are a number of suggestions and methods on this page...

Thx.

You mean just spray WD40 right on the affected area...? That won't harm the paint?

(Sorry if that's a dumb question, but I have no idea what's in WD40 and never would have thought of using it in this way.)

 

Yes, spray WD40 on the affected area. WD40 is a solvent, it's essentially mineral spirits which is the basic ingredient in bug and tar removers. It won't harm paint and will soften tar, sap, grease, etc. Basically, it's harmless although it's not somethign you would leave on your paint for a long period of time or let it dry in the sun, etc.

 

+1, works great for residue like that if the claybar doesn't work.

 

Will it cut through your layers of Zaino??

 

You should hit the area with polish and wax after you have cleaned it.

 

Well, just tried the WD40 and it didn't work.

I first sprayed onto a soft towel and tried rubbing. Nada. Then I sprayed directly on the crud and let it sit for a few minutes. Again, nada.

Guess I'll have to get some claybar and give that a try. Never used it before, so this will be a new experience.

 

Photos would be helpful.

 

OK, these aren't great, but it'll give you the idea...

 

daaaaaamn, that does look rank, really hope you get it off it doesnt do that paint justice

sorry bro

 

hope you get that taken care of quickly. try the clay bar. the longer it sets on the paint the harder it will be to get off. GL bro.

 

Thx, guys.

Plan to try the claybar over the weekend.
