What are your thoughts on slime? I have an old 1982 Honda three wheeler I am fixing up (exsisting thread) and it has a two piece rim that is a little rough. I blasted the mating surface but the problem is the pitting from rust. The old o-ring is cacked with rust. Right now I am cleaning up the o-ring and plan on running a thick bead of gasket maker on each side, setting old ring on and putting back together. At the same time I am wondering if slime would not seal the mating surface from outside the mating surface, while at the same time helping to stop any further rust problems. Any thoughts?
