I prefer Turtle Waxes ICE and products which are the best Ive ever seen since the 60s
I agree with Arthur, I like the ICE products....no icky white residue!
Mcquires. No if ands or buts
I use some stuff called Detailers Pro - it does a great job on my black car.
Here are some reviews of the top rated brands.
This really depends on whether you are waxing your car properly too. You could break out your finances for the most expensive brand of polish but still do a crap job.
