Hello - my name is Heather Lupu. I work for Guardian, the manufacturer of ShowerGuard.

When looking at products like Diamon-Fusion vs. ShowerGuard it's important to note that any product which repels water (like Diamon-Fusion or RainX) is derived from organic chemicals to some extent. It's these organic chemicals which cause water to repel off the glass. However, as with anything organic, they will break down over time. To be fully permanent, ShowerGuard is derived from solely inorganic chemicals. This means your enclosure will maintain its corrosion resistant qualities with zero reapplications. So, it isn't really a question of which product is better, but rather what type of coating are you looking for - one that will repel water (Diamon-Fusion) or one that will permanently protect your glass from corrosion (ShowerGuard)?

Another important thing to do is cross reference what each product offers. Here is what I found based upon the information available to you as the consumer:

CLEANING GUIDELINES for both products are fairly similar: the use of common household cleaners about once a week.

EASE OF DETECTION: Only ShowerGuard has a detector (most of our ShowerGuard Registered Dealers have these on hand when installing the glass) which can actually detect if the coating is present. This is important for installation quality and customer satisfaction.

WARRANTY: Diamon-Fusion offers a lifetime warranty (for the water repellent feature only) on all but automotive glass. If they feel your claim is valid, they send you replacement coating to apply to your glass. ShowerGuard has a lifetime limited warranty, in which we send a technician out to your home to look at the glass and, if it appears there is a problem, we pay for the replacement of new glass. Since the inception of our warranty system, we have never had a coating failure.

I hope this helps, please feel free to email me if you have any further questions at hlupu@guardian.com

Good information Heather. Well presented and seems fair to your competition too! Thanks! I'll look for your product in the future.

ANNEDC and hlupu I hope you will read this post from another similar string so you can see what wasn't said about our coatings. Ironwood Builders, I agree it sounded fair but it would only truly be fair if it were accurate.

I would like to shed some light on many of the comments made here as there is a lot of inaccurate info thrown about that needs to be corrected. We are DFI, the manufacturer and patent holder for Diamon-Fusion coatings.

The representative from Guardian stated that they need a detector to know if the coating is there. This is not the case with DFI coatings because they make the water so repellent that it acts like mercury, so it is obvious and visible with the water. Many of DFI's customers have the coating applied to both sides of the glass so knowing which side to put in is not critical but another way to know is to simply feel it.

WE offer a lifetime warranty on more than water repellent feature. Because we are a true thin film unlike their coating, we give a lifetime warranty against cracking, chipping, peeling, hazing and yellowing of the coating as well.

Treating the glass with our coatings fills in those pores so many of you have mentioned about untreated glass, so it feels MUCH slicker to the touch. The argument about corrosion vs water repellent resistance is not taking into account what actually occurs in a shower. Because glass treated with our coating is much more repellent, most of the water that carries the minerals that cause the milky white look is not on the glass long enough to do the damage AND because we fill in the pores, like a non stick pan in your kitchen, any spots that do remain come off easily with any cleaners.

The reason Guardian sends out a technician to check their coating if there is a problem is because they CAN"T as far as we know send a repair kit. It has to be done in a factory and can't be repaired in the field. Ours can be done at factories in chambers or hand applied in the field which is why it can be maintained to never in effect wear out.

Hydroshield is a simple silicone film that is not patented and has reasonably good consumer quality but you can purchase a better consumer applied product called ClearFusion V at Shopdfi.com and not only treat the new door, but all the other doors in your house for likely less money. DFi has shower door manufacturers around the world that have sold our coatings for over 15 years, why not ask a real reseller what his customers have told them?

I say real because the Glass Company above called ATM is not and has never been licensed to sell our patented process so that company never had a chamber as a license is required. That said maybe the person commenting worked somewhere that did have one but why stretch the truth here?

He commented on the chamber method not being as green as he thought but again the facts are that the Southern California Air Quality Management District has approved every chamber out there and they are the most strict section of the EPA.

ATM mentions a competitor Clearshield Ritec (whom we have independent test results that we outperform) and gives them a glowing recommendation but I have to say I doubt he knows about the independent testing that was done to quell all these baseless claims.

Again glass is quite porous IF IT HAS NOT BEEN TREATED. Squeegees work great but are what our coatings eliminate the need for when applied and maintained properly. I am sure some of you reading this are skeptical, so I will offer you a free small pre moistened towelette nanopax of a coating for you to try yourself. If you already have stains, no problem, let us know and we will give a small sample of stain remover as well so you can get a test area clean.

The picture I have attached is showing two pieces of glass with water dripped on both sides but only treated on one side so you can see the mercury effect. For those who want to take us up on the free samples mention Houzz and send request to info@diamonfusion.com Thanks for listening.

Diamon-Fusion International...my installers use and recommend your product...and we just put it into our latest job. Every story has two sides..my comments were meant to allow that Heather presented a reasonable and non-confrontational explanation of various finishes for shower doors. The accuracy of any presentation needs to be researched in my opinion.
