Plastic Warpage Repair Failure

["amc74hornet" <AMC74HORNET@xxxx>]

For those of you that own late 74 cars the big square hole below the side window where the seat belt comes through for the lap belt there is a big curved plastic filler. Mine were missing on the new car. I got 2 good ones for 10$ from a guy in Canada and recently got 2 really nice black ones from my friend. The problem is the good ones have some UV damage and are warped a little. The black ones are fine exxcept for a little bit of warpage. I figured i'd experiment a little on the black ones to remove the warp. I clamped the warp out of one of them and heated it real hot with a hair dryer and let it cool. Warp was still there when it cooled. I reclamped it and put it in my dehydrator and set the temp for 130 degrees and baked it for 4 hours. I let it cool and the warp was still there. The warp probably will not show once the parts are snapped into place since the mounting flanges are intact, but I had to give it a try to remove it. Today I will get out the SEM and paint all the small parts since the weather is going to be nice.
