I suspect your paintwork has already been damaged. The acidic substances in the bird poo eat into the paint, so the fact that what you have done so far hasnt worked, means this has most likely already started to happen, sorry!.

There are some things you can try to rectify the problem. Such as using something like t-cut to rub away the damaged paintwork. But you do have to be careful not to rub to much, or you will simply rub the paint away!. The idea is to peel off the damaged surface layer (hopefully the damage hasnt penetrated too deep) to leave a nice fresh finish.

But if you are a bit wary of undertaking this, i would recommend you taking the car to a professional car valeter as they will, or should have all the latest products available.

A long time ago i worked as a valeter and one time my boss took round a 7 series bmw, lovely metallic red, the car was less than a year old. It also had enormous swirling scratches all over the bonnet. The company director who owned the car decided the best way to remove bird poo was with a brillo pad!!.

Definately DO NOT use this method!!

I get this problem every year at this time, my driveway is used as a flight path and Im convinced they target the car. The surrounding driveway has nothing like the amount of poo the car has.

Badbusdriver's suggesion of T-Cut is good but I find the metalic paint version is slightly better. Dont just pub the mark itself, use a cloth pad and rub a bigger area and go gently, it takes patience, light pressure with a lot of passes. You can pretty well stop bird poo leaving marks if you use a modern polymer polish to clean the paint followed by a sealer like Autoglym Extra Gloss Protection. This works for me, even with the dreaded Sea Gull Poo, but I still hose it off as soon as possible.

Car paint is much thinner now than a few years ago. My 2014 Sharan has paint 90 to 120 micron thick but doing a sneaky test in the showroom new Golfs and Polos are around 70 micron. The main disadvantag is that corrective work like this is a lot more limited.

The most important thing is to get at it before the stuff hardens, and be gentle and persistent. After that it may be T-cut and polish, as stated above.

If you live near the sea, be specially aware that seagulls consume a lot of sand, which makes things much worse .... That can even mark glass if you aren't careful.

Try this for stubborn bird droppings. Soak a sponge in warm water and palce it over the offending mess. Leave a few minutes and have a peak. If it won't go just repeat after a few rubs just repeat. Did swmbo's car which had attracted the seagull airforce and removed the lot that way.

You need to wash the car with a quality car wash (not fairy liquid please!) then claybar it with something like bilt hamber clay. Beauty of this claybar is water is its natural lubricant so you dont need to buy any lube.

Roll the clay in your wet hands (so it doesnt stick to you) and flatten so its about 2" across. Rub the clay back and forth over the wetted area when the bird poop is. The clay will lift it off the paintwork. Fold the clay on itself and flatten out again, repeat on wetted body area.

You can do this all over the bodywork to lift unseen tar, grime and brake dust etc. When you look at the clay,you'll be amazed what you've taken off the paintwork.

Never ever clay a dry body panel. Do NOT use T Cut or other cutting compounds.
