Wrapping up final metal touches on my one ton. After I completed my running boards and steel I had to come back to fix an issue. My home made running boards turned out awesome except for one hiccup. I have a slight wave in both. I have been reading about oil can effect, but this wave seems excessively tight. Push down hard and it pops very loudly and moves noticeably. I'm not sure if this is in fact an oil can or if the panel itself has actually warped. I have been replanishing welds to little effect. However, I tried a small torch and quench but it scares me and seemed to make it worse. Also I'm not sure as to how to read an oil can and where heat should be applied. On the other hand, where would planishing be beneficial to drop this wave?
Thanks 😖
