Hi, I was able to correct via super glue down the inside edge were the body meets the chassis. Basically as you said, anchor the warped body to a straight chassis. In this case the chassis is nice and thick. Since warpage was slight, the correction worked wonderfully. Thanks to Tamiya for developing there tape, I used it to help keep things together while the glue dried. Funny, I initially complained about the tape but have since found 100%, my gripes are due to lack of experience and not the products.
