Nice shot!

I just used Hydro Blue last night. Damn, that was easy.

I washed the car with McKees soap, rinsed, applied Hydro Blue (used too much), rinsed, quickly dried it with a waffle weave, then put the car away since it was dark. This morning I was greeted by a smooth/slick finish and great shine. I am really surprised something so easy can work so well. I must be missing something...

The Chemistry minor in me wishes your comment stated "SiO[SUB]2[/SUB]" instead of "SiO2". :cheers:

I just applied McKee's coatings to paint, glass and wheels today; Will definitely add Hydro Blue to my wishlist for periodic maintenance of the coating.
 
Did the wife's car and as stated very was to use. Now waiting for kevinwelch and his reviews and his findings on spray coatings...
 
I wonder if this product would be worthwhile for non-enthusiasts. Of course it won't last very long if sprayed over an unclayed and unpolished surface, but I'm curious if it would do any better or worse than a typical wax or sealant applied to the same mediocre surface.

No matter what product you use, if you start with a mediocre surface you expect mediocre results.

McKees actually has a kit with a clay bar, iron remover, wash and si02 blue. Claying doesn't take too long and if your not worried about swirls etc this would be an awesome place to start. If you decontaminated the paint that would really help the longevity of any protection.
 
Still streaks but very little compared to the others.The streaking .If it streaks they wipe away with ease.Great product and user friendly.

Agreed, I expect most of us who prep properly will also use a wax, sealant, or regular coating rather than a "protect as you dry" spray. That's why I wonder if this would be a good product to recommend to people whose finish will otherwise get no more than a cheap wax once or twice a year. I might use a spray like this for coating maintenance, but it would never be the only protection over my clearcoat.

I want to be confident that I have complete and even coverage, I don't expect this product to provide the same level of protection and durability that can be had with traditional application, and I enjoy spending the extra time once in a while, even if it makes little or no difference. Often products that are quick and cheap tend to perform like they're quick and cheap in one way or another, whether that's the case here I have yet to observe.

I would agree with that statement. In my short term tests, these silica sprays do offer reasonable protection, but I think longevity is a big shortcoming. Perhaps that's overcome by the ease of reapplication.

That's why I prefer the concentrate myself cause you can dial in your ratio and use it weak and just use it often. Hydro2 at 7:1 works great every couple weeks. Sure beats spreading sealant or wax then buffing all off over some of today's large vehicles.

And that's why -- even if the RTU or manufacturer recommended dilutions of the concentrates last only 2-4 weeks -- I like these silica sprays. Most of us wash our cars every week (sometimes more, sometimes less), and blasting the car with these silica sprays takes all of 2 minutes. Followed up with a Master Blaster, and you've got a refreshed shiny hydrophobic surface!
 
Great review! Unfortunately there's no mentioning of approximate durability, HydrO2 gave me over 6 months which was unbelievable! I hope Mckee's stuff beats it! I'll be watching the comparison in the forum.. this stuff is interesting!
 
Forgot to ask about expiry.. is it like Carpro's 2 years shelf life? Thanks
 
They all advertise 3 months as the duration. Really surprised yours lasted 6 months. Did you have any wax or sealant under the HydrO2?

I did mine on April last year, Nothing was under it.. I gave it a really good clay and applied HydrO2, In November I decided to do a 2 step polishing and coating and I could see Hydr02 on some parts of the panels (I guess %30)
That was my daily driver, Now when I use it for the main purpose I bought it for, the corvette wheels, It gives me 2-3 months, I guess it doesn't like that much heat from the wheels but it's the quickest way to seal them.
 
Wow. That's good life out of HydrO2. How were you maintaining the paint during washes?
