Quoted from DazedandConfused:touché.
Regarding the problem of playfield glass shattering on the concrete, I believe Marco's Specialty website sells slip-on plastic corner covers, but have not found the item yet. I can't do much about the humidity, but sounds like I should do something about the cold. I will start by measuring the garage temps. The terranium heating pad idea sounds good, but I just wonder if those could malfunction and overheat the cab. I'll get circuit breakers right away. Merci.
pbl has some

I have those and my friend printed some off thinkverse using some rubbery material that I also use.
