I have some severely rotted out bottom of the cab on both sides,,,but REALLY bad on the passenger side,,,does anyone have any tips or sugesstions to fix these properly,,,i would like to replace with all new metal,,,and use the new glueing process most bodyshops use around here,,,apparenlty it's much better than welding,,,i also plan on having the bottoms coated with spray on bedliner material so they will never get chipped and rust again. . any ideas would be greatly appreciated
