Yellow spots on surface of my car

[jdubious]

I'm going with bug poop as well. I've found these on my car while parked outside less than 30 mins. Given the spot I was parked at there really is no other explanation. You have to get them off quick! I've had a couple that were left to fester for a while and experienced the same issue you describe, a yellowish spot about 1/4" in diameter on my white paint. My car is Opti-coated and while regular washing would remove the material in question the tinted spot remained. Clay bar helped fade it to almost unnoticeable. Over time they have either faded out or I just plain forgot exactly where to look for them.

Nice article, come to think of it there are trumpet vines growing adjacent to my driveway. They attract swarms of bees Oh well, I'm willing to cut them some slack given that without bees life on this planet would more or less cease to exist.

yeah it's bug poops. i get that on my SWP as well. if you use compound it gets off but you have rub it real hard. like others said, seems like it goes away in several days later when it's exposed to sun

Are these bird droppings, bugs, pollen, etc? I even tried liquid dish soap and it didn't come out.

What kind of trees have you been parking under?

I live in Northwestern WA state and I've learned not to park near the small Maples that everyone likes to plant in parking lots. I once left my motorbike in a spot slightly overhung by a maple for maybe two hours, and it took me at least that long to clean all the little sap drips off. These sap drops are evil and can even blow on a breeze. They're real small, maybe 1/32" in diameter. Luckily, my bike was a copper '03 SV1000S and I cleaned it that same day, but I have a feeling that if left they'd be capable of staining a clear coat. I take extra care to park away from the parking lot maples now.

A coworker tells me he has the same problem with the pines that overhang the driveway where he rents. He made a conscious decision NOT to buy an AP2 S2000 until he moved because the pine sap has RUINED the clear coat on his little red '90's Civic hatch.

As was already mentioned, don't use dish soap.

I'd probably do a paste-wax every weekend until those stains go away, but that's just me personally, I have an unreasonable fear of taking power-tools to my car.

Try not to park under a tree especially if its raining or look like its about to rain. Clay bar then wax helps but sun will remove it in a few days.

I'll likely just look for a bunch of How-To videos on YouTube. Seems legit.

or pay someone to do it, i recommend NorthWest Auto Salon in lynnwood, they do amazing work.

I used to use claybar, but just tried a Nanoskin towel the other day. WAY faster and last longer too! But i'll still keep a clay bar for small areas or when there's a tough spot.
