I have used:

Zymol Auto Bathe: nice but Mequirs Gold Class is comparable.

Zymol HD Cleanse: works great, easy to apply and take off. Does not do much on swirl marks.

Zymol Carbon: nice product but it is excercise to apply, no chalky residue...pricey....does not last too long.

3M: swirl remover (dark cars), gloss enhancer, imperial paste glaze-all the 3M products contain mineral oil and this makes it wierd. The wax and gloss enhancer take alot of polishing. The swirl remover did not do much. Does not last long.

Meguiars; cleaner wax, show car glaze, final inspection,-ok, easy to apply but leaves chalky residue and does not last long.

I want to try next:

P21S Cleaner wax
P21S Multi Cleaner
P21S Concourse Carnuba

Zaino Brothers (do I need the Z-2 or Z-3?)
