OK my turn for some feedback about Meguiar's product experience.
I contacted the local rep about their products and selection (for VIC - Ossie Palma @ 0419 590 699) - very good product support and knowledge. I was given absolutely every single instruction on how to wash (!) and apply different layers of different products with what cloths/micro-fibres etc.. Also - a list of products to buy, where to best buy them from, when, who to speak to to get the right price and everything. Ossie's help was just great. I've got a complete list of products to use from scratch to final finish if anyone needs it - I can e-mail it.
Anyway - I equipped myself with Ultimate Car Wash + NXT Gen Tech Wax 2.0 Liquid, some cleaning cloths, wheel cleaner and drying materials. Since it was my first full car wax manually - I spent a long time on the complete process but the result - blown away. The car looks like new. Please note - let nobody tell you that the liquid wax can be applied in less than 30 minutes because it can't, unless you're using a professional AC powered applicator and on a small/compact car. Together wish full car wash, wax, wheel cleaning and interior cleaning - it took me ±2.5 hours. I'm sure with more experience the waxing procedure will take less and less time. Anyway - I'm not going anywhere else, the Meguiar's products have got me completely and the car looks just stunning (black Lexy 250 is a treat to look at when sparkling / mirror clean).
