I keep mine in my beer fridge cuz I don't drink beer

I use a nice soft bristle paint brush.

O.K. I am a new guy and please forgive me for saying this. I know we are to be discrete when it comes to other companies products. That being said Turtle wax ice full stength not the detail junk but the full strength stuff makes white marks go away. I bought some years ago cause it was suppose to be the best thing going. They lied it's junk on paint but it does makes the white marks go away.
