For about 3 years I have been a Zaino Brothers Show Car Polish fan. But recently, after seeing some results of the New Meguiar's NXT Generation Tech Wax on an old 1940 Packard, I gave it a try.
Wow this is good stuff. Does not leave dust or static. Easy on and off. It is very much worthy of your consideration. It is a polymer and thus is not a wax. One part. You can do a Cobra in about 2 hours if you are slow.
Meguiars' has two products. One is in a squeez bottle and is a thickish licquid. The other is in a spray bottle and it is for touch up after the use of the squeeze bottle product.
I would give this a try. At $15 per bottle, you cannot go wrong. Multiple coats builds up the shine and it hides swirl marks. Leaves no white powder or residue. I used white cotton towels to take off the wax and lightly buff it out (which is easy BTW).
I do not know if this product is available yet in Austrailia but I am sure it will be soon. It has just hit the shelves here in the US over the last 4 months.
