I've been called a whacko once already so I'll continue to expose myself to that moniker, but doesn't it occur to people that maybe acid rain had an effect on that paint? Sometimes also the history of the truck can make a difference. Vehicles here used as commuter vehicles by employees to the chemical plants nearly all without fail have peeling paint.
From what I understand GM started with water based paint in the mid 80s' and freely acknowledge they had issues in the earlier years. Toyota immensely improved on it in the late 90's and I truly think the manufacturers have it somewhat under control. Of course the method they use and the product that 4onthefloor is going to test are completely different. I'll be interested in seeing how it turns out.
