Alcohol For Cooling Windshields

I only use old fashioned H2O. I don't drink... maybe that's why...

NO denatured alcohol! Just use Isopropyl rubbing alcohol.
The reason for using alcohol in a 50/50 mix is simple. When it is applied to the glass, the alcohol "flashs" off the glass which in turn takes the heat along with it. It is amazing how great it actually works. Just use either a repair "band aid" or a piece of electrical tape to keep it covered when you do this. We have found this to work best when sprayed on the glass with a spray bottle. Spray light to start then keep adding slowly till cool. keep a towel handy to wipe after the alcohol flashs off and the water part warms up from the heat coming out.

Well, since Jeff will probably delete this thread anyhow.....

This "flash" effect is also known as the Martini Effect.

A good Martini (stirred, not shaken), is prepared by placing ice, gin (or vodka) and vermouth (if desired) in a glass mixing cup (not stainless steel). The stirrer is then inserted and one stirs clockwise or counterclockwise (depending upon the hemisphere you are in;) and keeps the stirrer in contact with the glass at all times. The friction created by the rubbing of the stirrer against the glass, draws the heat out of the beverage, transfers it to the glass and it is then dissipated. Strain into chilled martini glass and enjoy \:D/

DaveC,

I can't help but notice the quality of your posts has gone significantly downhill since you have been trying to catch the Coitster in total post count.

Now that we know how to make a good Martini, can we get back to windshield repair???

I use the same technique as sydfloyd44.

I spray the mist starting about a foot away from the damage all around. This draws heat away from the affected area.

Using a 50/50 mix rather than undiluted results in a less dramatic cooling shock to the w/s. Repeat that until you can put the back of your hand against the damaged area with little or no discomfort.

The same solution is also ideal for cleaning the w/s after as well as cleaning off any resin on one's hands and/or fingers during.

It will, however, dry out your skin so use it for the latter with some degree of prudence unless you also use hand cream.

One addendum to above post.

I really don't bother to cover the repair but watch carefully to assure that no water runs into it.

If one does prefer to cover it, I would refrain from using any material with adhesive placed directly on the repair area. No sense implanting anything else that needs to be cleaned out before commencing the repair.
