Hi all I am in the final stages of replacing many floor panels/lower cab corners/ mounting brackets etc and I still find holes to be welded but I am getting tired of the weld/grind. Is it okay to simply use a short strand fibre or all metal to skim the seams and then epoxy later. Or do I have to bite the bullet and drudge along with more hole finding, cooper backing weld and grind?
The other thought was to use a under coat spray?
It depends on what you are going for. Do you want it to be a perfect/show truck? No, cut it out and weld in patch panels.
Do you want to seal it, have it be pretty smooth, and stick some paint on it to protect it and make it shiny? If so, pick your method. A skim coat of fiberglass or bondo will smooth out the roughness and let you make it shiny.
It won't be perfect, but it will keep the rust off and let you paint and enjoy it.
