So far on my relatively new Saphire Silver Crossfire Coupe I have used the Zaino products. Dawn wash, clay, Z2 Pro with ZFX (4 layers with Z6 between layers). This week after a wash I tried topping tha Zaino with Duragloss Aquawax and the shine enhacement and slickness was much better than the Zaino Z6. It was amazing! I have yet to try additional layers of Zaino after the AW. It should be compatible. All Zaino and Duragloss applied by hand.

I use megs products on my old black (with metalflake) Nissan 300ZX with excellent results. I tried Zaino but the Megs worked better on my 18 year old paint. Used Megs M83 and M80 with a Dual Action machine, then M7 and M21 by hand. The old Z car looks incredible.
