Remind me to let Charlie Morgan build my boats, but not work on my car. There have been major issues with brake rotors warping and failing because greasemonkeys were over-torquing lug nuts. There is no such thing as "as tight as a car wheel" because the proper torque ratings vary over a wide wide range, and using any one number for all lug nuts will leave some loose, and others creating damage.
Case in point, mine are spec'd to about 75 ft.lb. but most shops and dealers have set them to 125-150ft.lb., where even a breaker bar can barely budge them. This, despite express warnings from the car makers.
If the designer has done their job properly, there is a default SAE, ASTM, etc. torque rating for each size/grade of bolt, and that is the rating which "should" be used. If the designer took that into account and built the hull layup to match. If someone used generous bolts and intended them to be under-torqued..."properly" torquing them might damage the glass, I'd guess.
Kinda like going to a casino, no matter what you do, the odds are against you.
