When the product was presented to me it was touted as a product very different from RainX.  I was told that it formed a molecular bond with my windshield.  Not only would it provide RainX type features, but I was told that it would help my windshield resist chips and cracks - in fact I was told it game with a windshield warranty!   I had always loved the effect that RainX had on my windshield, but did not enjoy having to reapply it every few months.  The prospect of a product that would not have to be re-applied appealed to me very much.  The over $300 price tag didn't seem like much, especially with the 4 year warranty that was promised.

After picking up my vehicle I was amazed at the performance.  When driving at any speed over 45 MPH I would not even have to have my windshield wipers on.  The product would shed water so well it would just slide off.  I was impressed.

It is now April of 2007 - only 3 months after I purchased my vehicle and had the Diamon-Fusion Product applied at the dealer.  The water beading effect is totally gone.  When comparing my windshield to the other auto glass on my vehicle, it has no better qualities than the rest of my glass.

I had asked at the time of purchase if any maintenance was required.  The dealer told me no, however I did receive a spay bottle in the mail from Diamon-Fusion shortly after purchasing the vehicle stating that if the effect was wearing off I could renew it by applying this spay.  

The prospect of bringing my vehicle back to the dealer every 3 months to have it reapplied over the course of the next 3 years does not sit well with me.

I figure I could purchase about 42 bottles of RainX for what I paid for this one application of Diamon-Fusion.  And bringing my vehicle in for a reapplication is far more time consuming than if I just applied the RainX myself.

I wish I had discovered this article before my purchase:

When doing searchs I find it helpful to also try Diamond Fusion (with a "d" at the end)  as many people get them confused.

After mentioning my issues to one of the service advisors I was told that yes you do have to apply the maintenance spray regularly.  I was told there was nothing that they could do.  I asked how is that any different than using RainX?  I was told that you still have the anti-glare properties (I really don't notice that) and that I have the guarantee of windhsield replacement should I ever get a crack.  I thought maybe the warranty would be worth it.

When reviewing the warranty document that I received when I picked up my vehicle, I discovered the following:

• I only have a standard warranty.  To get winshield replacement if it is determined that the windshield is not repairable required the "Replacement Plus Warranty".  I was never offered this option, yet I was told that repair/replacement was part of the warranty.
• Here is what the standard warranty covers:  "Covers repair costs only, not the replacement of the whindshield.  For any windshield damage described herein which is deemed non-repairable, the customer must pay for the cost of the replacement at the time of the replacement.  Whishield damage is deemed non-repairable if said chip or crack lies in the direct vision of the driver, if the crack is over 6 inches in length, if there is an actual hole in the glass, or if the repair compromises the overall integrity of the windshield."   

Heck, based on all of that when will they ever pay to fix a chip or crack?

Based on my expereince, purchase glass coverage from your auto insurance agent and buy a few bottles of RainX.
