Any suggestions here? The problem might be that I'm using Turtle Wax Platinum High Gloss... great shine, but it streaks when I try to dry my car with both a chamois cloth and 100% cotton towel.

For anyone considering the Turtle Wax Platinum High Gloss... stay away. It's a pain to apply, and the white residue gets stuck everywhere. Don't know why I made the switch from Meguiar's NXT... it's easily my favorite.

after switching to Zaino, there is no going back to anything else for me
