BS? Go to Zaino's website and read up there. I personally don't use Zaino, but it IS one of the better products out there. Here, I'll save you the trouble, and read #3 below:
ZAINO APPLICATION TIPS
1. Because Zaino Show Car Polish is optically perfect (99.9%) The optimum results are achieved by using over wax free paint.
2. If you are looking for the ultimate paint surface preparation. Use Z-18™ ClayBar first or skip to Step 3.
Zaino Z-18™ ClayBar was designed to remove airborne contaminants, paint overspray, water spots, rail dust, industrial fallout, diesel fuel & catalytic converter residue and any other bonded surface contaminants from paint. All cars even brand new factory paint has airborne contaminants... Here's the deal. The non-abrasive Z-18™ ClayBar will remove any surface contaminants from the paint finish and not hurt the clear-coat. The ClayBar will get that paint finish smooth as glass. Now remember waterspots, bird droppings and bug guts if left on the paint finish for any length of time, will etch into the paint finish. The ClayBar will also remove any store bought waxes....
I recommend you use my car wash (Z-7) as a lubricant for the ClayBar. Just make sure to keep the surface area lubricated while using the ClayBar. Use 1/2 capful of Z-7 Car Wash to 12 ounces of water. I use a spray bottle for the mix. Shake it up and spray the area to be Clayed. Just make sure to keep the surface area lubricated while using the ClayBar.
3. I would definitely recommend you remove the wax buildup on your paint. Just use Liquid Dawn (hand dishwashing liquid) as a car wash. It has a high alkaline content which cuts right thru carnauba wax, paraffin, silicone oils, etc. This will get your paint finish squeeky clean and wax free.
I don't advise making a habit of washing your car with Dawn. But for this scenario it's fine. High alkaline products like Dawn are tough on polishes. It will never harm the paint finish though. A car wash is made specifically to clean without removing durable polishes. ALSO, Make sure you remove any water spots, before you apply my products. Because Zaino has no abrasives or harsh solvents it will not remove water spots or stains. Z-18 ClayBar is great for removing any paint surface contaminants. Re-wash the entire vehicle with Z-7 Car Wash immediately after the ClayBar
Cleaning Process.
Also, go to autogeeks and autopias forums and read there too. There is absolutely nothing wrong with Dawn, used once or twice a year to do a FULL strip of all surface products.
And before you call anyone an a$$hole, maybe you should:
1. Not avoid the profanity filter, lest you get a vacation.
2. Ask if that particular person, in this case me, if I actually KNOW Stangless first and am just giving him "gas." The answer, if it concerns you at all, is yes.
