Silica Spray Showdown: McKee's v. Gyeon v. CarPro

[WRAPT C5Z06]

I'm still not certain about which is better.

If you think about wetting ability, the more hydrophobic a surface it is, the less wetting ability. You'll have better contact angles with beads. But, beads stay put until they are evaporated or blown off. If beads stay on the surface, and if they have mineral deposits, they might cause etching in the LSP or clear coat.

For sheeting, if a LSP sheets well, it gets the water off the surface. Gone. So, I'd think sheeting is a better predictor of protection because it gets water off the surface.

But, that's just my opinion. They both may be equal markers of protection. Perhaps the beading is a better predictor of hydrophobicity, but I'm not sure it's a better predictor of protection. Both may be indicators of protection, but I don't know truly which is the better indicator.

Makes sense. What I do know is, sheeting isn't a strong characteristic of these silica sprays compared to other coatings and sealants.

Agreed.

Frankly, this is the first time I've applied any of these products to a completely prepped paint surface. I've always used them on wheels or boosters.

Dedicated coatings have much better "sheeting."

I appreciate you taking the time and effort to post this up and do a review and test for us here! Thanks again!

Non-essential update.

Cleaned the hood with the 1:128 dilution of McKee`s N914. This stuff let the MF just glide across the entire panel except where the taping marks were - not entirely surprised.

N914 on Panel A/Product A


On Panel B/Product B


On Panel C/Product C


Freshly cleaned!






There`s a single water spot (Panel A) that didn`t come out with N914. Normally I would try a little Gyeon Spot remover and then move up to CarPro spotless, but I didn`t want to affect the coating.

Beading isn't as crisp on panel C. A seems to be the best, although, the beading still isn't "tight"

Are you referring to the newest pics? If so, I agree with you, but whenever I spray a rinseless or waterless wash, in my opinion, beads aren't always perfect. I suspect it's the surfactants, but that's a guess. Does anyone else typically see this? Even with Uber with it's glossifying polymers....

I don't judge a product by cleaning beads. You are trying to encapsulate dirt dust etc. it's not a normal pure water or rain water you will see on the surface. "Leave nothing behind " may be the case but it brings something to start with to do its encapsulating, cleaning, lubricating and clean release. If not you might as well just use water

Yes, the newest pics.

Wait so no one still knows what the A B AND c are correct? We all find out at the same time?

I never judge beads by a liquid that comes out of a spray bottle, so I don't think I've ever took the time to notice.
