My thinking, nope and yes.
Some have painted the windshield around the edges. I have not heard of anyone getting the fog out. That would be nice.
You won't have a problem getting windshields. Jim K and others have them. I have been told that normal glass shops can get them. Don't know that to be true.
Dan,
always taking rocks but none seem to crack my fogged windshields.

That reminds me of my route 66 trip--I got a good size rock on the LH side and finally I was able to replace the fogged windshield. After about 15 years, I've had 2 more--on the LH side of course. The RH one is still fogged and seems to be impervious to rocks  Maybe I need to drive on the other side of the road. BTW, a long time ago I saw an article on how to remove the fog. IIRC it involved a hairdryer and lot's of patience with unpredictable results. I think it may have been posted here.

Sammy,
IIRC the fogging is caused by moisture permeating the "plastic" material in
between the two pieces of glass.
People have tried clothes iron, heat guns, etc. without success. They have
reported that the windshields crack.
Replacement windscreens are available from any of GMC vendors such as Jim K,
Jim B, Alex Sirum, Tom Hampton, etc.
Someone noted that if you coat the edges of the windshields with silicone
RTV sealing off the "plastic" material in the center it might prevent the
windshield fogging again.

Rob M.

Is there any way to get the 'fog' out of the windshields of gmc motorhomes?
If not is replacements available? S. Williams

The fogging is probably not moisture. It is the leaching of plasticizer from the plastic. Plasticizers are chemicals that are put into plastic when it is manufactured to keep the plastic from getting hard and brittle. For example we have all seen how some dashboard plastic panels crack in the sun. They don't do this right away -- only when the plasticizer has evaporated out of the plastic. If it were just moisture then the hot sun on the windshield would take it out -- better than trying a blow dryer or heat gun which likely would break the glass.

Emery,
I did a search for fogged windshields on the forum and below you will find a
message you sent in awhile back.
I've saved it in my GMC - Windshield folder for future reference.

Subject: Re: [GMCnet] Fixing fogged Windshields - Possible?
This is a common misconception. The "fogging" is not the laminate
becoming "unglued". Over the last several decades, the most common
material has been polyvinyl butyal, or PVB, a plasticized film that is
sealed under heat and pressure to form a cohesive laminated glass
panel. It is not glued to the glass but sort of "melts" to bond them
together.
What is happening is that the plasticizer used in the laminate is
absorbing chemicals from the rubber seal surrounding the edge and also
oxidizing from the oxygen in the air.
Newer windshields are using a different plastic and are not as
susceptible to the "fogging" problem.
You are correct that heat can help with this problem but to do it you
would have to put the whole windshield into an oven and heat it up
very slowly. The windshield would have to be supported by its
original shaped mold to prevent sagging and distortion when heated
close to the glass melting point.
If you were to try to use a hot air heat gun you would likely crack
the windshield as there is no way that you could heat it evenly and no
way you could get it to the temperature needed to reverse the problem.

What's really sad, is that when you replace them and think " that's done, I'll not have to do that again" in 2 years they are fogged again.

A friend of mine in the glass business said that's it isn't moisture, but the glass separating and the plastic returning to its original translucent state.
The cure is heat (to its plastic state) in a vacuum chamber, like when the windshield was made. The cost would be equal to a new one.
When we try to heat the glass it cracks, because the hole glass has to be heated evenly, to attain equal expansion of the glass.
Has anyone sealed the edge of a new windshield with some good sealing product, to see if it delays the delamination?
My tidbit,as told to me.

Just keep the coach in Phoenix. My coach has no fogging and the glass is probably original...

Regarding "Fogged Windshields" on page 127, in the classified section of the March issue of Family Motor Coaching magazine from FMCA is the following ad:

I think they are referring to dual pane or thermopane side windows that have moisture between them--a different issue than the laminate layer between our windshields. Maybe someone can come up with a laser "dermotoligy" approach.
