Good review and I completely agree with it but would also add my biggest bug bear with the product - horrendous juddering of the wipers. I applied this to both my and my wife’s car (having first used the dedicated cleaner) and within days my wife was asking what the hell I had done to her car. This stuff was relentlessly promoted by the usual ‘influencers’ some time ago which should have set the alarm bells ringing for me.

i believe a lot of this companies products were based on fluorine chemistry which was the subject of global bans due to ‘forever chemicals’ and many have been reformulated to address this (think also their waxes). I just wonder if the reformulated products are just not as durable as their previous incarnations. I still like their waxes (as I don’t mind reapplying frequently) but I can’t get on with the windscreen product.

 

I've read so many comments about these products. I was so pleased with mine that I coated a friend's brand new A3. Yeahhhhhh..... he's still never been honest with me because I did it for free, but I'm guessing it went wrong. And in a similar way to what you're saying.
On your other point, you may be on to something there. If you're into cycling or running, you'll know the best waterproof material ever created is Gore Shakedry. However, they stopped production of that due to the use of flouro chemicals..... which are coincidentally what made Fusso so good.

 

Nice write up @newtona1.

I was just about to ask what made you go for this over Ultra glaco? From what I've read between the two, the ultra glaco is the superior product.

I've not applied a glass coating before but a while ago when I did consider it, I narrowed it down to the following products...

1. Anglewax H2G0
2. Ultra glaco
3. Diamond protech

The idea was to start with the cheapest but still highly rated product and then if that failed, work down the list.

However upon more research, I just decided against it for the reasons you mention above. It just seems to be too problematic, varying experiences even with the same products, so what work for some may not work for others, in the end I decided I don't want to go through the faff and tbh, I'm happy to just use my wipers lol.

I do however have a bottle of H2G0 which I am going to apply to the rest of my glass windows (not the windscreen), was meant to apply this last week but didn't get a chance so hopefully get to that within next few weeks.

 

I'd never done a proper coating, and given the variable nature of success with these products, I opted for the cheaper of the two Glaco products. If it failed, I'd only spent £10 instead of nearer £20.
Thing is, when DX performed, it was hysterically laugh out loud funny to watch water just disappear over the roof. Genuinely a superb safety feature as it greatly increased visibility when you need it most.
So since DX worked and I've never had so much as a squeak out of the Bosch Aero twins, I'm gonna get Glaco Ultra on when it arrives and hopefully be able to give some positive feedback
Cheers for letting me know what you ended up doing

 

I used the product for 12 months, and 1 coating did nearly last the whole 12 months for me.

What I did not like about it:

Water did not move off the screen until nearly doing 60mph.

And in winter the windscreen was becoming caked in ice as the water never ran off sitting overnight.

I have went back to using H2GO, and the water moves off at 30mph and from my past experience of using it in winter there was little water left on the screen to freeze.

 

Do you mean Glaco Ultra lasted a full year?

 

As Ultra user this was helpfull as I'd been wondering about the latest all singing dancing 'DX', which I'll now not bother with
Mind, I loath coatings on the windscreen, just use an all the other glass. Windscreen for me are best just super clean, polished cerium, then for wash routine Bar Keepers Friend as a final step, even keep some in the boot in case wipers start smearing a bit and a spray of Mixtra doesnt relieve the smearing when out and about.

 

Totally agree. Goes on sides and rear, which probably helps with cleaning. Though I'm currently trying Stjarnagloss Parla on the sides because curiousity.
And yes, after the windscreen had been cleaned and polished, you could just leave it at that, but.... curiosity wins again!

 

as well as the "temp range to apply"
you have to consider the Rake of windscreen
pressure applied by Wipers
how much/little you use wipers
what screen wash you use / how often you use/how much per use....



ive tried Glaco on the windscreen, after a Full on prep , over and above there instructions, and had it fail faster than yours did
and cause problems needing a Full on prep to get the last remaining smearing/blurring off the screen when it Did fail

but,, i use Volvo screen wash, diluted to -10 in winter 0 in summer, that Cleans the screen,
wiper blades were new Gen volvo ones, cleaned before fitting , cleaned at every wash of the car,,
windscreen got a Pressure rinse every wash to make Sure there couldnt be any shampoo or snow foam left on it, or the scuttle,,
the glass cleaner they sell aint too shabby tho, the one with the built in felt pad,

i went Back to Gtechniq on the side / rear glass and the screen is as clean as it gets nothing on that thank you

 

Great write up fairplay,not used it myself so can’t comment currently useing megs compund and glass sealent or tge old realibale cheap tried and tested rainx 2in1 on dad mams/family cars

 

that kinda proves it for me
Different windscreen rakes, wiper pressue sweep / diriving conditions etc Some work for some perfectly and Not everyone.
as i Never got on with "rainX" at all, ok it was a far few years ago i last tried it and doubtless its formulation will have changed. All i got was "rainbow smears" smudges/haze and wipers skipping/noise . it came Off very easy tho,, rotary/glass polish compound and a "cheesed" off me/5l pump sprayer to keep the glass cool,, and clean up in all the isles

 

I used Glaco Ultra on mine and the wife’s car (2014 and 2019 Yaris) and have had good results. Both cars have Bosch Aerotwin Wipers.

I’ve long since binned the packaging but I remember on the back it had a graph depicting how much performance you should expect to drop off as time passes. To my recollection that graph broadly seems accurate.

i had to remove the coating on my windscreen because of a silly experiment which left the screen with really bad water spots. In the process of removing said spots I removed the Glaco from affected area so ended up doing a full strip of the screen and reapplication.

I did a winter Decon about 10 days ago and it was definitely still going on my Yaris. The windscreen coating was from 31/01/24. At motorway speeds I wouldn’t need to use wipers (as long as there was nothing in front spraying my windscreen). The coating on the side windows was from 30/11/23 and still going very strong, like it was freshly applied.

I don’t get to drive the wife’s car often but her Glaco was put on 22/12/23. She has started complaining that the windscreen seems to be a bit smeary/foggy so I assume it’s starting to break down now. Her car is a daily runner and has only been washed 4 times since then so it’s pretty impressive imo.

Both applications were done the same. GT Decon shampoo contact wash, towel dried, BH cleanser fluid wipe down and then application.

I can only assume there was something on the packaging which suggested against applying in cold weather. I keep a cleaning record and when I apply LSP’s/coatings on so I can decide which stuff to buy again/ditch (the looks from my wife when I tell her about it 🤣) etc and there’s a very specific note for when I applied Glaco on my Yaris that it was a very cold day.

I recoated with Gyeon Q2 View Quartz. That’s what I planned to use originally but then I came across Glaco and it has a much easier application so I used that instead. Q2 view is a lot more of a pain to apply with the cleanse stage. Results are good though, I would say marginally better than Glaco (and possibly just a placebo effect due to being a fresh coating). When the time comes for recoating, I’ll probably go back to something easier to apply like Glaco or something similar.

 

A cleaning record is an absolute must.
Dedicated is just what the lazy call obsessed! 🤣

 

I have used a few coatings on the screen over the years, and when I was driving 500 miles per week on motorways I barely had to use the wipers (actually had the wiper motor seize on a car with lack of use) with many of the coatings which prolonged the life. My driving has now changed to mainly urban/country road and average speed over a day is about 45mph.

 

Is there a difference in performance between Glaco Ultra and DX? I had two tries with Ultra. First time juddering appeared after few weeks. Thinking it was my fault I changed the wipers to bosh and applied it again. But juddering came back quite quickly and soon after that once wipers were on the smudging. Curious if DX would behave the same on the same car. I don’t mind applying it more often, providing it will work well.
