Hey there Jafo,
As someone who details cars on the side bird crap on car paint work is a nightmare.
If the stain is just a ring mark left over from the crap it will be easy to remove. As you have stated that you used cut & polish to try and remove the stain then its a little worse than the normal.
What I would recommend is getting it to a panel shop and have them buff the car. If you have the gear yourself then get some.
* 3M Rubbing compound, it comes in a 1ltr black plastic bottle.
* 3M Perfect-it Polishing Pad Glaze, comes in a 1ltr black plastic bottle.
* Woollen Buffing Pad.
* 3M foam waffle pad.
* You will need to use a buffing machine to achive the best results.
* Use a wool pad to do your cutting and spray the compound with a little water, this just softens the stuff a little.
* Set the speed of the buffer to about 900 to 1200 rpms... if its any faster you need to be carefull not to rub the paint off.
* Use the rubbing compound on the whole roof not just the affected area as you will notice a big difference one you have done the roof.
* You can just test it first on one of the spots and see if it goes. Then do the whole roof.
* Once you have completed that wash of the excess as if its left to dry its very hard to get off.
* Change the woollen pad for the black foam waffle pad to use the buffing polish.
* Then use the Perfect-it polish to finish off the job, this product is great, it will remove any swerls on the paint surface and can be used on the whole car by itself. This product can be used by hand also, its good for removing those CAT scratches on the bonnet...
* Use a little water with the polish also as it increases the heat when buffing which will give you the show room shine gloss on your paint.
* After all that give the car a realy good wash as this stuff flicks everywhere.
* Then finaly touch the paint off with some good quality carnubawax (excuse the spelling).
Wear some shitty clothes as it can get a little messy... hehe but its great fun!!...
Hope this is some help to you, I know it seems long but I thought I'd step it out so as to not confuse anyone... If you need more info give me a hoi.
Cheers
Phil
