The interior front portion of my cab roof is riddled with little rust holes. How would you recommend patching that? Weld in a new panel or new sheet metal? Fiberglass? Marglass? Bondo? My truck is going to be a driver and will have some plastic filler on it so I'm not requiring that everything be patched with metal. At the same time I don't want to cut corners and want my work to last for many years. What would you suggest?
