A car with black paint seems to be a pain in the @ss for paint correction.
Whats your favorite technique?

I tried microfiber-red-yellow-black where the scratches were heavy and let me happy.
What do you prefer?

Water spots especially when theyve been for years are another pain,
I work them with red pad and OXIDATION REMOVER , i know theres a product for that but the OR gives me a heavier cut.
Ive seen for pads especially for window polishig, whats the difference? are they good for the DA? heat transfer to the plate?
Many people say its better a rotary for window working , but I dont have one.
