My friend just bought an old BMW 318i 2004, he asked me to polish the car.
As usual I started with Sonax Tar Remover, I sprayed the whole car, let it sat for 2 min, then I sprayed Chemical Guys Bug and Tar Remover (2 cap mix with water in Chemical Guys cannon foam), left it for 1 min then I jet it with water.
Later, after cleaning 4 wheels and I opened the doors, I found It had water spots on door frame, just the center of the B pillar where they stick the rear door in. The water spots were little bit white. (See pic)
I managed to use Wolfgang total swirls remover 3.0 to remove some of them but very hard to do it by hand especially rack and gaps.
Later, I found on passenger side front and rear door, there were marks also but it seem to be under the clear coat, cannot buff it of.
When it dried, the car is totally normal, but when it wet, I easily can see those marks. More over, if I drop some water, leave it there for 2-3 min, there will be a small light blue mark. Although you can wipe the water, the spot will stay there for 3-5 min then disappear.

I really have no idea, did I mix the CG bug and tar remover too strong? (First time I used it). Or because the Sonax tar remover interact with Chemical guys? Why the rest of the car was fine but only in those areas?
Please help me. Thank you!
