I've not tried coating myself, but from quite many places that I've read, you might have a bigger issue with coatings.
1) it will etch into the coating if left on for a long time just like your clear coat
2) needs polishing to remove the etching and coat that small section again

It's expensive and not a miracle product, imo just a stronger and longer lasting "wax/sealant" that requires less frequent maintenance but a more complex maintenance procedure. If the shop that you're doing it have great warranty and after sales service then it's fine. (just imo, don't blast me )

That's true, went to my friend's house to check out his dad's E300, the amount of stone chips on it after just 1.5 year is painful to see.

Well, mainly because clear bra/ppf is another level of expensive?
Not sure about partial (front only) ppf, but AutoDetailer Studio is offering them at RM1x,xxx. That's way out of league for many people though, and not that logic when the ppf cost like 1/10 of the car. That's probably why it's only common for those people owning exotic cars. *but I am aware some shops offering coating service that cost almost like that figure

True also, so many unknown brand of coatings and there's no real enforcement on who can apply it and etc. And if dig hard enough you'll see some shops hiring foreign workers to "detail" the car. *includes Rxgxx Vxxxt, you can actually see in one of autxbxzz video

*disclaimer, go figure the xx by yourself, don't want mention full name. Scared later get in trouble, who knows if they stumble upon this post.

I'm using Gyeon view, so far it's good but I won't say it's really amazing and not very diy friendly plus it's not cheap (currently RM3xx for the kit). 3 months in and it's still holding up but speed below 80kph(maybe my car's aerodynamic is not good enough)needs to use wiper and if you follow other cars on the highway, it will be less effective (perhaps slipstreaming). Also need to learn not to keep using your wiper or it will significantly shorten the lifespan of the coating.

I think it might be better getting a very good pair of wipers such as PIAA silicone wiper and etc. I have a few friends that are using PIAA and good feedback overall. (application needs to pay some attention in cleaning, will affect how good it performs) But one caveat is silicone wipers can actually scratch your windscreen slowly if you always use it dry/not wet enough.

Don't try to use Rain X or cheap coating on your windscreen, it's not worth it, fails very quick and the residue may affect your wiper performance and visibility after that. However they are pretty good for side windows )

Hope this helps.

How frequent do you need to reapply? I've tried other ppl's cars with rain X on the windscreen, wiper judder with Bosch OE wipers, not sure if it's application problem.

However they are really good for side windows, a must for rainy season, mine lasted about 4months before it starts to show signs of wearing off.

I see, that still last quite long on the windshield.

Any tips for glass polishing? Not sure if autoglym glass polish uses cerium oxide, I do have some problem working with ceriglass, getting some marring after polishing with rayon pad.

That beading can rival some pro coatings d
And that's a nice shine too.

I think it should work, and I've seen people done it with a proper car painting spray gun.

Well for DIY, I think it's better to practice first, or else it will just be a mess of orange peel and possibly trapped bubbles. I've not tried it myself as my car is so old that it has glass headlamp covers

Perfect combo?

Hahaha, I know. Just as a 2 step combination, it's probably as easy as it gets. Will try later to see how they perform.

Not available locally

I am also using soft99 ultra glaco on windscreen, so far only complaint is wiper judder when used with windscreen wash concentrate like Bosch for example. Maybe next up is try their own glaco windscreen wash liquid, which manufacturer recommends.

I’ve used proper glass coating in the past, Gyeon View. Only lasted 8 months with semi-shaded condo parking. When it failed, the wiper started to smear and streak as if there’s heavy oil film. The price, preparation work and longevity, I am not sure if it’s worth the effort. At least for this specific coating.

Also used PIAA Si-tech for about 2 years, car under the sun 90% of the time. Had hard water spots issues with rain water baked on dry by hot sun, etched right into the “silicone coating” that the wiper lay down. It affected hydrophobicity and vision in heavy rain (Rainy night, brake lights and oncoming traffic will highlight all the watermarks). At 2 years mark, it also slightly hardened, and started streaking. Also not worth the price imho, could’ve gotten 4 sets of Bosch rubbers, a set of Ultra glaco and glass refresh with extra change.

Currently I am back to using simple Bosch rubber wipers and ultra glaco, apply 2 - 3 times a year if necessary. Affordable, quick, effective.

Sorry to bump a reply from so long ago. I believe what you had is road grime/dirt bonded to your paint/sealant, unfortunately it’s very obvious on light coloured cars, not restricted to white cars only.

From your photo looked like there were some high and low spots of the Fusso coat since it does not appear exactly like normal watermarks etching. I had similar issue before with some wax as well, got most of it out by using a clay bar. Removing it by polishing works too, but may not be the best method as one should always start with least aggressive method. Some may argue must polish after claying since that install swirls and marring too, depends on the assessment of the detailer, ymmv.

There are quite a few “ceramic” sealants or sprays that can last 1-2 months easily and have comparable water beading behaviour like fusso coat in the market now. Perhaps you can try, and can’t avoid routine wash for light coloured cars, it’s a lifestyle

Our weather is quite harsh at times, raining for awhile and hot sun right after. Water spots get baked on immediately, also depending on where you use your car mostly, if industrial area then it’s worse. Happened to my car too as it’s almost outdoors 24/7, just different pattern due to the water behaviour from product used.

Also possible to be a fusso coat issue, not unheard of, perhaps try other sealants as suggested by other members above. Continue to wash periodically and clay it perhaps once a year/when necessary. It’s not easy to have a light coloured car in tip top shape all year round.

Nowadays there are clay towel products in the market. Pricing wise fluctuate a lot, reputable seller should be around RM4x and above.

Please use some form of lubrication when claying, best is use clay lube. In a pinch, use car wash shampoo solution.

If all sounds too much of a hassle, go find a proper detailing shop do a polish package maybe. Don't bother with those normal/roadside car wash place.

It's one of the best for windows, one application can easily last a year. Affordable too.

Not suitable for windscreen with wipers from my experience, usually use Soft99 ultra glaco for that.

I actually wanted to try their windscreen washer fluid too. Did it work well in getting rid of road films or bugs?

Free advertisement. Only JPJ saman if your number plate not up to spec, you want to stick with double sided tape also SC can't say anything.

Yeah, noticed that as well. iirc Tesla one is just a Tesla logo, clean looking.

I also removed mine from my car, prefer a clean look.
