I have been working the Revell Porsche 918 and the Revell Mazda Rx-7 kits for quite a while and really want to finish them to start some new ones, but I am being held back from finishing them. Both of the chassis' are warped. I have already painted them and want to know if you have any suggestions on how to fix the warp and also if anyone else is having the same problem. Thanks, Matt.
