To be fair, I have seen some REALLY crappy factory paint jobs over the years!Ya know I did an old tractor with a roller and thinned out Tremclad and I was surprised how smooth and well it worked. Much better than the brush job I was doing beforehand. However I have not been impressed by how fast the paint oxidized and went chalky.
Anyone here have the paint fall off their GM, while they were trying to figure out Low VOC Paints? They were definitely not the only manufacturer affected, either.
I had a VW that had been looped through the paint line about six times, as best I could tell. When the paint started peeling off in large chips, if you picked up the chip and looked at it under magnification, it looked like one of those stacked layer Licorice Allsort candies. Black, grey, repeating, on down to the metal.
For the price, it's hard to beat Tremclad. But the low price DOES come with a cost too!
I ponder whether a coat of clear, sprayed over the Tremclad, would offset some of the issues with chalking up?
Over the years I have slung Laquer, enamel, poly-urethane, and epoxies, they all have their adaptation curves.
