So yesterday when returning to my car after work I found some bird poo down the side of my car, so straight away I pulled out some Quik Detailer and cleaned it off, but the area where the poo was seem to have a matt finish to it So as soon as I got home I washed the area and then had to use Scratch X to have any effect on it, after some hard hand polishing the gloss finish was return but if you look closely you could see some etching. I've seen people on here complaining about this on Audi paint but didn't know how bad it really looked, kind of puts me off buying another Audi, my black corrolla I had before you could leave bird poo on for several days and it didn't effect the paint. The bit I really don't understand is that last night I had a lovely gloss finish to the area that you had to look hard at to see the etching but when I check my car again today after work the area had gone matt again . It was like polishing it out last night was just a dream! So does any one have a theory on what is going on here? Was it that my car has been in brightly sunlight all day and the heat has effected it (it's Moro blue so gets quite hot)? Is the etching in the clear coat or is something from the bird poo sitting underneath it on top of the colour coat and the heat has cause it to leach back into the clear coat turning it matt again? Do Audi really care about this issue or are they only interested in grabing your money and running?
