RainX vs. Zaino?

1524 Views 6 Replies 3 Participants Last post by  mikedan
The thread about RainX application concerned me regarding my finish. Since a small amount of RainX would have to come off whenever rain hit it, eventually all the RainX on the glass would be washed over the paint. I wanted to make sure that RainX wouldn't hurt the Zaino I so carefully applied.

I sent my question to Sal Zaino. I'm posting the question and reply below for all to see and comment on.

>>>Hi Sal, just a quick question for you on Turkey Day. I want to apply RainX to my windshield and back window of my SUV. I've got Zaino on the paint. Will I have any problems with the rain running down over the painted surfaces?

Nope.... no problem...

>>>Have you had any reports of such problems? I would doubt there would be concern, but I thought I'd check with the pro first.

I'm not found of RainX... It leaves a film and can distort your vision, especially a night...

Z-6 works great on clean exterior glass. It will leave a high polished finish that repels water and makes the wiper blades work better... Remember Z-6 is extremely concentrated, a little goes a long way....

Another Tip is... You can also use Z-2 on the exterior windows. The combination of Z-2 and Z-6 is awesome on exterior glass... and preferred by many of my customers....:)

Z-6 is also safe for use on aftermarket window tint.

mikedan....this is MOST interesting. I was not aware of Zaino application on windows. Never discussed this with Sal, but I am glad you did.

I do know that I have accidentally applied z2 and z6 on my windows...it came right off, but I never checked its rain-aversion properties.

I will give it a try on my side windows and "see"..;)
OK, I Z'd up my side windows and mirrors. The 1,000,000 question, though, is what can/should/do I use to clean my windshield after I Z'd it and 40 bugs hit it along with road grime, sludge and grease....

WITHOUT taking the Zaino off?

After all RainX will stick almost forever no matter what you use to clean the dirt off.

And as good as Z is, don't think it is formulated to clean up bug goo too!

:D

Left an email for Sal....will post his response as soon as I get it.

Sal answered:

"Stoners should work fine as long as you don't use it constantly..

Let me know..."

Well, I will give it a try on the Ody and see what happens. No question, Z is easier to apply and buff than R-X. But will it last as long????

Stay tuned....

I'm pretty low tech here, but during the high bug season I'd first wash the windows with Zymol along with the rest of the car, and then rinse and chamois. When the windows really needed a good cleaning, I just used regular old Windex. The RainX held its own for 4-5 months, which is about what I expected.

I think any of these products are OK, as long as they have an 'X' or a 'Z' in their name :)
Well, the verdict is in and my mind is made up. No question R-X is better in the rain/sleet/snow than is Zaino. Took both cars out today in the coooooold freezing rain.

While the Ody with Zaino on the windshield produced a fair amount of beading and sheeting, my MDX with RainX on the windshield performed far better. I rarely had to turn my wipers on with R-X, whereas with Zaino, I had to keep them on. The beads of water simply were not clearing off the windshield on their own very fast.

So I think I will stick with R-X on the windows and Zaino everywhere else.
Good info!

Thanks for the side-by-side comparison, Oct. I'll be applying some RainX to my windshield and back window tonite. I've used it before, so I'll make sure not to use too much.
