As for wear and tear on hands, I guess it all depends on whose hands are on the tools and speaks volumes for real not armchair mechanical ability.
As for winsheild prices, when I did glass in Dallas, lots of yankee glassmen, some from the up in the motor city way said that the glass business up there was the chits. If you can negoiate prices, they knew what they were talking about. When we had people want to negoiate, we'd tell them have a nice day.
As for the seat covers, I found it rather an easy process, but skill, aptiude, hand strenght might be a factor I am overlooking when I rate the difficulty of a repair.
