In the red corner: G1 SmartVision Clear Glass- This long distance fighter has the ability to go strong for twelve rounds. G1 forms a chemical bond to the glass which lasts up to 24 months, but the application can be a little more involved (particuarly the removal of the product from the glass).

In the blue corner: G5 Water Repellent Coating - If you prefer a fighter that is smooth and slick, floats like a butterfly, and repels waters like a Lotus Plant, then G5 is who you should place your money on. G5 comes out of the gate like a banshee hell-bent on sheeting water like Manny Pacquiao slapping a speed bag. G5 provides more intense water beading but only has the gas to go three rounds.

And the winner is.....: The Glass! You really cannot go wrong with either G1 or G5; both products are exceptional performers. If you desire easier application and removal (think RainX easy) then G5 Water Repellent Coating is your guy! While it "only" will last six months, which is longer than just about anything else (accept G1) it creates intense water beading that begins to evacuate water as low as 25 mph.

On the flip side, if you don't mind the more difficult removal of G1 ClearVision Smart Glass (think of Angelo Dundee having to tame Muhammed Ali in the gym) then your choice is easy. G1 provides near the water beading levels of G5, but will maintain that level for up to 24 months or 30k miles.

If you desire the best of both worlds (Sugar Ray Robinson in his prime) you can apply G5 Water Repellent Coating over G1 ClearVision Smart Glass. The choice is yours, and perhaps even better, you simply cannot go wrong.

Winners Are Made In The Gym: While the fight against rain gives both of these stars a chance to show case their skills, remember that it is the training camp or prep work where the winner is determined. For best results clean your glass thoroughly and polish with Gtechniq G4 Glass Nano Polish.
 
I saw G5 the other day and I was thinking of trying it out. I have a bottle of G1 that I ordered but I was sick the week I got it and it rained all last week. I'm hoping I can use it this week. I might give G5 a try on my truck.
 
i still think for the price, glass science has some really decent products with a very slick finish (Rain Clear Windshield Repellant Gel). gtechniq definitely has the longevity edge.

I have a tube of the Glass Science Gel. For some reason I just can't get my hands around this product. Every time I use it is smears and becomes a big mess..:mad::mad:

i hear that, i've found it works best on a polished windshield and have had that problem when i applied it over a windshield coated with something else i wasn't aware of. :)
 
Will the use of glass cleaners like Meguiars Perfect Clarity compromise the durability of these coatings?

I tried G5 for the first time today. Applied thin, as I tried to remove it I had a ton of streaking. Looks like oil on my windshield. I thought OK, maybe it needs to dry, left it sit 20 mins and I was still like I was just wiping the oil around.

Any experience with this? Am I doing something wrong?
 
G1 is a fabulous product. It's super easy to apply and after some initial clean up you're left with crystal clear glass. Since it was raining on Friday I went for a drive and intentionally didn't use my wipers.... that's how effective G1 is at shedding water....:bigups

Sounds like you had some kind of residue on your glass. Did you do an IPA wipe down before applying G5?

G1 leaves a lot of streaking behind and this could be intentional in order for the user to ensure that he's obtained complete coverage.

G2, which smells an awful lot like Isopropyl Alcohol, is used to remove the streaks. After applying G2 use a cotton cloth to buff clean...
 
Bobby I used G5, which is also greasy.

I wash with regular car soap, then use Glass Science scrub, dried then applied. Directions on the bottle are vague.

I ended up using IAP today to remove the grease that it left. Probably stripped the product as well. Have to wait until it rains.

You might be surprised. G1 sets up and cures pretty fast so if it the application set for about 10 minutes before the Isopropyl Alcohol you might be OK..

You're right, the instructions for application and cleanup could be a hole lot better. I think including a paper insert in the plastic bag or more elaborate instructions of the web page...

Isn't G techniq EXO another choice for use on glass?
Click to expand...

Yes EXO can be applied on top of any Gtechniq coating (C1/G1/etc) or by itself to any surface. I am going to detail my motorcycle and use the specific Gtechniq product to each surface, then top the entire thing with EXO.

I am not sure about G5, but it will not effect the durability of G1.

Interesting. I have used G5 several times, and by constantly switching to a paper towel, I have had zero streaking. I would wipe the surface first with IPA.

It may have or may not. I know it will not strip G1, but I am not 100% on G5.
 
Ill try the IPA wipe before application next time. Its supposed to rain today so Ill know if my post IPA wipe down to get rid of the oil on striped G5
