Has anybody had experience with some of the economy line acrylic urethane paints currently available? PPG's Omni line is one, Matrix paint systems is another. My truck a 50 is used as a truck, but it also lives in the garage when not being driven. The thought of spending the money on the Dupont's of the world when I know it will get dings and scratches is hard to justify. It currently has 15 year old PPG Deltron acrylic urethane on it and I'm getting ready to freshen it up for a repaint. Any thoughts would be appreciated. Thanks, John
