I just bought boat load of stuff from Autogeek (coupons and discounts get you) and their sister company, including Clay bar and lube. Now you enticed me about this product. You see I'm kind of layed back, but I want the best results with the least amount of work. (you know what I mean). Thanks for the post.
Startup with Zaino can seem a bit overwhelming until you get through the process once.
Start with a good scrubdown or two with Dawn. Next step is claybar. Don't overspend on lube. Seems silly to use a spray bottle of expensive detailer. I did that the first time, then tried a couple capfuls of Zaino car wash in a spray bottle. It worked great, and cost a few cents instead of $20, so feel free to use liberally.
One more wash down after you're finished with clay, to get rid of the soap residue. Check before and after claying a section with the ziplock bag trick. You'll be surprised at the difference in feel. What seems like a smooth surface when you wipe it with your hand feels like exposed aggregate with a baggie on your hand.
I've had great luck using Zaino's Fusion (Z-PC) with my Porter Cable polisher to work on swirls and scratches. Use as needed with a bright light to check progress. I then use Z All In One with the power polisher to go over the whole truck. That's all I do on my daily drivers, but get a little carried away on the SSR.
Zaino stresses in their information that less is more. Use very little of Z2 or Z5. I haven't used ZFX in years. I confirmed with Sal Zaino that the primary function of ZFX is to speed up the process so you can do multiple coats in one day. I'm quite happy to do one coat a day while the truck is off the road - can't put it on the road till mid-April, so lots of time to get the job done. Once you have wiped off the residue from Z2 or Z5, give it a quick going over with Zaino spray detailer to make sure all the residue has been removed. Bright light helps with this as well.
What I found works best when putting on Z2 or Z5 is to keep spraying the applicator between panels so it stays damp. I have a sprayer with distilled water (no idea why, but it's got to be better than tap water, right?). I alternate between water and detailer. The product should go on extremely thin. Awesome result with multiple layers.
You won't believe how slippery the finish will be, and how well it beads when wet. It is impossible to get masking tape to stick, and duct tape will barely hang on. I do the same process every spring. The rest of the season, I spray it down with my power washer to get rid of any grit, wash it with Zaino car wash using Joshvette's two bucket system and one of those ridicculously expensive wooly mamoth or whatever mitts, dry it with compressed air to minimize possible swirling and finish with detailer.
