I’ve had a problem with warped GlaStar doors after storing them in a hot location. If I were to do it over, I’d stand them up in a rack in a place that doesn’t get overly warm. I ended up having to use 2x4s and large C clamps to pull the doors back into shape a little at a time. I used a heat gun to retrain them with each small correction, heating the area till it was just starting to get hot to the touch. Much trial and error to get a nice fit. But the experience was very educational and recreational
