Thanks to some Instagram knowledge bombs I was able to fix the bent wing on the Mazda 787b in literally 30 seconds.
I know there are a lot of probably easy methods out there, but this is the one I used and it was mad easy.
Just dunk the rear end of the car into some hot (not boiling, but basically the hottest your kitchen tap will go) water and hold it there for ~30 seconds. Adjust the wing as needed, and holding it in the correct position, rinse under cold water to set the position and voila: straight wing!
