Airborne Contaminants Needing Identifcation And Prevention On Car Paint.

[tangcoral]

My week old white car is beginning to show its paint's weakness against contaminants.

Mind you the car has been sealed with liquid sealant to protect it from the harsh elements.

While I was away for 3 days my car was left under my house car port.

Today I noticed a few (6 spots) yellowish gummy sap like tiny droplets on random areas of the car.

Giving it a car wash the "droppings" were easily removed but it left a faint yellow stain which was easily seen on the white paint.

What is it? Looks like something off a tree or flower pollen of some sort but the nearest tree is 50 meters away mind you it was under a car port.

How can I get it out or did it embbed into the paint? Was I late in washing and removing it?

I thought to use clay but it looks as if it is embedded. Didnt know something like this can penetrate the clear coat within a couple days.

EDIT: After a short internet research, I am thinking it could of been bug/insect related like poop/gut/mucus as the car port is brightly lit with long fluorescent light. just a thought..

First thing to try is ... soak a couple of pieces of toilet tissue in water, squeeze together and then put on the mark, if the tissue starts to dry out before the mark goes ... repeat ... works for me.

Tried your suggestion but still left a yellow stain.

It looks like a tiny droplet of dried mustard.

What is it?

Think you must try fine cutting compound then put loads of quality polish build up.

Actually it didn't work on my new Pearl White V-Cross today either! I then tried a clay, then Auto Glym paint renovator, it's finer that a cutting compound ... got some of it out and planned to get something more course. Anyway I polished it with Wolfgang Deep Gloss Paint Sealent. Went out for a drive and when I got back the mark had gone! Wonder if something bleached it.

I have to admit that the very same thing happened on my previous metallic silver car ... mark disappeared whilst out driving after doing same.

I think my brown stain was lizzard droppings. I now cover the roof with a large cloth ... think I'll have to get a proper cover as the lizzards seem to live above where I park in the drive.

This happened to every white car I owned as well. They too were left under a carport at all times. A wax that came in an orange bottle removed it including the stain. I don't recall the name but it can be found at any auto section of a Tesco or Big C and it is in an orange colored bottle.

If the car already had a coat of sealant, then the 6 spots of sap will just be on top and washing won't remove it. Just use a clay bar and re-do the sealant. Just my two-cents; Bilt-Hamber is the best I've personally tried, you can order it direct from the UK via their website.

The thing is, the mustard yellow colored dropping is easily removed with a simple car wash but it leaves a yellowish spot much like a dye.

It kinda smears a yellowish dye when I apply pressure to it with a wet finger only if the dropping are fresh 12-24 hours.

I tried using IPA rubbing alcohol to see if it was some type of organic dye. Anyhow claying doesnt work as there is nothing really to remove, it seems to have penetrated past the clear coat.

I'm shocked that something like this can penetrate so easily even fresh droppings (12-24 hours)

Is it lizard dropping? its literally the size of tip of a dull pencil.

'kinhell ... this morning two spots on my white bonnet ... only the roof was covered ... it is waxey ... so wash with water, then rub with washing up liquid, then a little paint renovator and finally re-polish with Wolfgang. I'm fed up already with white!! Definately here comes a cover!!

Yep, underneath the cover will be blanket type material ... I've read elsewhere of the scratch problem.

Now my wife, who like other Thai wives, knows everything in the world! Says it flys and actually she might be right as I have just seen them on and another mark just appeared ... came off easy.

Anyway thanks for the advice

If they are the same yellow dots I see on my cars (approx 2-3mm diameter, Amercian mustard yellow), I have leanrt to just let them go - after a few washes and some sunlight they dissapear.

Trying to get rid of them in one go would mean working your paint too hard, too frequently IMHO.

As for origins, the ones we get comes from some type of plant, unfortunately though, a horticulturalist I'm not

Yes Mr MRO ... I noticed that ... polished over and then found that they had disappeared next time I looked ... thought that it was either my old eyes or the sun bleaching them out ... I posted that earlier ... yes I certainly don't want to renovate the paint ... car is covered up now ... thanks
