Micro Pits on Paintwork

[zey]

Recently it had been raining alot. Today I parked my car under the sun and I noticed that my paintwork has got lots of micro pits (millions). Initially, I thought it's due to some paint overspray, but upon inspecting the windscreen glass, it's still silky smooth, hence I'm sure it's not due to that reason. I was wondering could it be due to acid rain? Or oil droplets in the air (from kitchen cooker fan exhaust)? Or any other possibilities?

I pulled out my PC, and applied two times of DACP with W-8006 on the bonnet. It seems to improve quite alot, but still there are some left. I believe rotary with wool levelling pad would be a more time-saving tool.

Please advice...thanks!

This actually doesn't sound very good. Hopefully whatever caused the problem is an isolated incident. As far as taking a wool pad and any type of cleaner to your car's finish, remember you have a limited amount of film-build.

You might get away with it this time, but if it continues to happen every time it rains and you leave your car in the sun, then it might be time for a car cover?

Just thinking ahead here...

Mike, I had been trying very hard to figure out when and what causes the pitting. I never park under the trees nor any industrial area. I wonder whether cooking oil will cause pitting on paintwork?

As for hard-to-reach areas, I plan to use Scratch-X, I wonder would it be aggressive enough...
