Dan,
In some cases that applies to painters too. A few years ago I stopped at a local body and paint shop to look at a Cobra I saw there and see if it was from around here. Their chief painter, being an arrogant a** Ho** informed me he hated those damn fiberglass cars and normally would only work on Corvettes and do custom paint jobs. I asked him what the Corvette bodies were made of and he informed me that any idiot knew they were good old American steel.
