SR coating vs dog slobber

[Guest streetsounds]

the slobber at my house is cool too I got jwf ss20 no prob but I have seen it on trucks mostly with dogs in the front seat

Have F1 on my cars and Vista on my home with 2 large dogs, and no problems. Of course I clean the windows pretty often. I would think leaving anything on the windows for a long period of time would mess any film up.

The 3M prestige film has a very thin scratch coating , nearly non existent. This was a problem from the very start when the decisions were being made concerning the adhesive and whteher to use a detac coating (they opted no-to save costs)

The first time I hear that a dog had licked off the color on a prestige 40 was 2005.

I particularly get a kick when a 3M dealer tells a client that only 3M film stands up to Windex. Ironic - -isn't it?

We had the sr coating flake off our work van passenger window from an installers sweaty arm (jwf sp25)

If I were to take an uneducated guess as to why this would happen, and this would pertain to many makers of film and NOT just one. and or 2 films made by a certain manufacture. This would be my guess.

Hydrolysis of (1→4)-β-linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in a peptidoglycan and between N-acetyl-D-glucosamine residues in chitodextrins

dog slobber And sweat as well and even if you were to cry on the film for a period of time same outcome.

Too many big words. Need to invest in a medical dictionary.

Never thought something like dog slobber would get this much attention from window tinters.......LOL

That's crazy.....dude came in a few months ago and said his dog's drool was making the tint flake, I told him he was crazy, we him charged and re-did the windows, but I sure thought he was full of it...

I find this thread to be absolutely fascinating.

I have a friend who is a veterinarian and as a result of this thread, I plan on asking her everything she knows about the saliva ph of a healthy canine. I do know that it is slightly higher than 7.0, but one would think it would have to be substantially more acidic (or alkaline) to damage the hardcoat!

If we were to test the pH of the tap water from all of our customers, I would imagine we would get readings well outside of what normal dog saliva would be. In my own home, the pH of the tap water is 6.2, necessitating our installing a water neutralizer to prevent damage to the pipes and plumbing fixtures. Many of my neighbors do not have neutralizers. What if one of them hired an installer to tint their home and he filled his sprayer from their kitchen tap?

If dog slobber can damage the hard coat, what impact does acidic or alkaline tap water have on the adhesive? Should we be testing our water? If out of spec, should we be using distilled? What is the impact of the dish soap & shampoo on the application solution pH?

I had the privilege of chatting with several technical staff members from CP throughout the years and they have long suspected that acidic or alkaline water plays a role in long term adhesive breakdown. A recall them saying "Water is wierd". They're a pretty smart bunch over there. I bet they were on to something.

If I learn anything more - I will post it.

Happy Thanksgiving to All,

too much crap to worry about
