It was years ago. The question popped up on r.a.h
How to make a low cost vacuum pump.

Yep, that windshield repair kit sounds good. Some enlightened auto
insurance companies will fix a chip "free" (without applying your
deductible) just to keep the problem from growing into an expensive
windshield replacement.

For a general purpose vacuum pump, I use a compressor out of an old window
AC unit. Mine has lasted for many years of occasional use. I store it
sealed up in a plastic 5-gallon bucket.

True, some will, and others will encourage a replacement as soon as it's
even remotely warranted. The truth is that most automobile windshields are
surprisingly cheap today--after adjusting for inflation, they are just a few
cents on the dollar of what they were forty years ago. Even the classic car
windshields have gone down a lot after abjusting for inflation; but the
greater difference is in the mounting methods on the newer (meaning the last
thirth or more years) cars--the replacement windshield will not be under
stress.
