Ah yes i saw that post regarding your car getting swirls, i believe it was really a lose-lose situation, anyways i hope all goes well with the swirls

Ok for your first question, using Elevo watermark remover will definitely remove any beading on your windshield, the reason is because it utilizes powerful acids the dissolve the watermarks ( actually to break down the mineral that form the watermark ) or at least soften them to a point where its very easy to remove already, using acids however no matter how light like vinegar would weaken any existing beading on your windshield because of the acids chemical reaction, so if you want your windshield to bead again you simply need to apply another layer of glass coating where Rain Clear specifically gel type would do a great job.

For question number 2, it depends on what you mean by better, Glass Science combo it made for removing road film and only the lightest of water marks, this kit is better in the sense that it is not harmful to the rubber seal around the windshield and other rubber and plastic parts, another advantage of this would be ease of use. Elevo and Rainclear however is on a totally different ballgame, elevo is used to remove moderate watermarks and is definitely better at removing around 80% of the common watermarks you see on cars, its definitely better but the downside is that you really have to be careful about the rubber seals, using elevo watermark remover also requires you use a biodegradable glass cleaner after to remove any remaining acidic residue on the glass before you apply rain clear gel, so the answer again depends on what you plan on doing, if you are going to remove watermarks the elevo is your best bet, if you are just planning on removing wiper hazing and roadfilm then glass scurb is easier to use not necessarily better but easier and safer, then again i don't think you could buy rainclear gel solo, i haven't seen a place here sell it solo they usually sell the kit that comes with glass scrub.

normally if the car comes out of the dealership, then it is not coated, coated windshield are those coated with Aquapel, Diamond nano Fusion, PPG Glass coating to name some chemical glass coating, of course there's also nano-tech-sleeve, PPG glass coating film and Cryztal glass film which are like screen protectors applied on the windows, if you find another layer of like a clear tint on your glass then its probably film treated and if your windows bead like hell for months then your glass probably has some chemical glass coating, one indicator that your windows still have some coating is when you actually don't develop watermarks or the water marks easily come off the window with just a hard wipe, and none of the above mentioned products AFAIK are available here, we even had to import our aquapel and some german name i can't even remember to treat our glasses, but Rain Clear to be honest is very very close to them in terms of performance, those more expensive coatings just last a lot longer and are "undisturbed" even if you use soap on your windshield washer solution. So unless you had them treated of you requested to have the car pre-installed with water repellent glass then your car should be safe to use with elevo watermark remover.
Thanks for your response ms madkatz!! galing mo talaga!!!

Follow up questions po...

What biodegradable glass cleaner would you recommend for cleaning the windshield after using Elevo? Are all glass cleaners biodegradable? Can I just use car shampoo to remove the acid?

I will return the Spray type GS Rain Clear and replace it with the gel type later
