Re: Rocker panel repair?
The only repair that's going to really last is to weld in new panels. Body fillers only provide a place for moisture to hide. Fiberglass does the same thing although it may last longer. Unfortunately body work is very expensive and not many people know how to do it right (that's why my tub has holes in the rockers). If it's a replacement tub can you put off the swap until you have saved enough for the repairs? I have done repairs like you are wanting to do in my early auto fix-up days and every time I wished I had just waited and done it right.
