Default Paint issue

Any thoughts on what this is? Washed the car today after several road trips. There are two small spots that seem adhered or burned in. Will not come off with rubbing compound. about 1/4" in diameter.

Not sure what it is, maybe sap? Try some tar and sap remover. It also looks like you might want to clay your car. Lots of little contaminants in those pics.

Good luck

I have never seen or heard of anything looking like this before.

You said you used rubbing compound to no affect. Have you tried rubbing alcohol or acetone?

Knee-jerk reaction is some asshat cig-burned it while you were on your trip.

You should be able to take that out with a mild polish and if you don't have a buffer you could do it by hand. If the mild polish does not get it then use a little more aggressive polish cmpound like Meguiar's M205. This is not a big problem and should be easily resolved. That spot could be a bird dropping that sat in the sun.

Use the buffer but try using the mild polish first. Don't let the buffer sit on that one spot too long or you will burn the paint. If that doesn't work then use a more aggressive compound. Also, it's important you use a cutting pad instead of a waxing pad.

Looks like maybe a chemical burn. Do you remember perhaps driving under a train trussell with a stalled chemical car overhead?

Would recommend clay bar first, follow with wet sanding, 1500, 2500 then 3000 grit. Compound and polish after that.

If it was a cigarette burn there wouldn't be any white in the center. I'm leaning towards the "damn birds" theory.

MrMik001, there are two types of rubbing compound, light/mild and "heavy" (duty) compound. With vigorous elbow grease, if neither compound had any effect on the marks, then machine compounding won't do ANY better. (that is to suggest, if you don't know how to use an electric polisher/buffer, leave it alone--you can do by hand anything that can be done with a power buffer, it just takes longer) It looks like one of the spots has a ridge around the lower half of its' circle in 4th and 6th photos; it's also darker in the lower half, both indicating that a liquid drip of some kind has "sagged" on the painted surface. If that's true, something "spilled" onto the clear coat. I'd suggest a tar or sap remover, like Jaylar suggested.

In 15 years of auto (repair) painting, I've never seen a cigarette burn on a paint job-- but the clearcoat doesn't look melted. It could be that the quality of the pictures don't display that well enough (no offense intended) AND there's no perspective in any of the photos--(are these vertical or horizontal panels? if they are vertical panels, those very well could be burns because drips on a vertical panel would run)--but my best evaluation is that something dripped and should be removable with a mild chemical intended for such a purpose (wax and grease remover, tar and sap remover, etc.)

You might take it to a body shop and ask them to tell you what it might be; from there, you can figure out how to clean it. They might even suggest a method.

Does it look like it's indented into the clear coat or sitting on top of it? From the one pic it looks like its sitting on top of it.

How about taking the car to a paint expert before you mess up with sand paper, buffing etc.

The paint expert will use sand paper, buffing, etc. also. Detailing is not exactly rocket science. It can be easily learned. Techniques you cite are commonly used and many here are adept as using the tools of the detailing trade.

Is this paint protection film? Mine has picked up some small stains that I can't get out. Tar/bug guts not sure. I think the film is somewhat more porous than the paint itself and things can adhere to it.

What brand PPF do you have on your ride?

The key is expert. If the OP is skilled in paint work, fine. If not, let someone who has experience do it. A mistake with sand paper will end up being fixed by an expert anyway. And, it is his car so it is his call.
