John, I have had good luck with using the headlight polishing kits that
are sold at auto parts stores. The kits are not expensive compared to a
new windshield. Try it on the windshield in a small area and see if it
helps out.

Jack H/Kolbers:
Doubt the polishing kit would correct my problem. The failure is in the
generic polycarbonate I used last time I replaced windshield and doors. I
think if I had stuck with more expensive GE Lexan, I wouldn't be having this
problem.
Right now I am scratching my head to figure out why this polycarbonate
failed. One possibility is a reaction to the last windshield cover I made
about 4 or 5 years ago. I found some heavy material, similar to Naugahyde,
at a local fabric shop. I was tired of making new covers out of plastic
table cloths every year. My thought is there was a chemical reaction from
the gassing of the material used to make the material. Maybe not. I don't
know.
Darn shame though. The surface of the polycarbonate is in great shape.
Thanks for the suggestion.

Subject: | : Kolb-List:Windshield plastic crazing |
John H and Kolb List,
I'm no expert on the polycarbonates or acrylics, but could this crazing be from
internal stress over time? Meaning that when you take a flat sheet and bend it
into a curve, then fasten it down into that curved position (the shape of the
Kolb nose cone), there is a small stress put into the plastic. Over a long period
of time, perhaps the stresses eventually cause the internal cracks or difference
in transparency?? This is a wild-a$$ guess on my part.
Most "airplane" windshields are thermoformed, heated until the plastic is soft,
so perhaps the internal stress is not as much?
If this is not a viable explanation, perhaps the previous suggestion of a bad batch
of plastic is the likely answer IMHO.
Most of the manufacturers have a website or some sort of tech help phone number
where you can ask a technical question. They may have seen this problem before
and have a useful answer.

Stress may very well be the culprit. Takes a lot of pressure to conform 1/8 polycarbonate
to the nose pod and upper windshield frame. Doors are 1/16, but
not much pressure to bend them to conform.
Thanks for the suggestion.

John,
One more suggestion. Tooth paste contains a mild abrasive. Take a tube
and put some on your finger and rub it on the outer surface over a small
area. Just like you are trying to polish the surface. Then clean off the
surface with a soft towel and pear through the affected area. If it looks
better, further polishing out will be of benefit.

Depends on the type of gasoline.
I used to be able to tell which would and which wouldn't damage the
glass. Been too long to remember that.
Some won't and some will. The types that will are immediate reactions.
You watch it and cry.
