Thought I'd post it here so it doesn't get lost in The Car Cleaning Thread.
A while back when cleaning the car I discovered these markings on my bonnet.
It appears at some point a bird has pooped on the car and it hasn't been wiped off and therefore damaging the paint.
I've tried Autoglym Super Resin Polish, G3 scratch remover, Scratch X and Ultimate Compound. The ultimate compound has faded the mark quite a bit from the 2nd picture. But I still cannot get these marks out. Any methods of getting this out? I'm led to believe the damage has already gone too far though.
Just to also add, I do not own a machine polisher and I got a local "scratch repair" guy come out and he attempted to use his rotary polisher with 3M Medium Cut and he only held the polisher on for about 5 seconds and said that he could not get it out without damaging the paint and he reckons it's been resprayed in the past and suggested I just live with it. I did notice however this guy did not make any attempt to clean the bonnet first (didn't wash it, clay it etc) he just dumped the polisher straight on to the mark and could have potentially rubbed dirt into my paintwork causing more damage. I got the impression the guy was in a hurry as he cancelled his appointment on me about 3 times beforehand and drove a little clapped out minivan.
Was this guy telling the truth? Is it really not possible to get rid of these marks without a bonnet respray?
