Highbuild primers over bodywork can be brushed on just over the area, that works fine.
You could brush on epoxy if you wanted to, but only if it's sandable, and you have a small spot here and there.............but I would spray the whole thing after bringing it all down to metal. Remember, epoxy is one of the only finishes that you could actualy do your bodywork over on......after scuffing of course.
As for how to spray it........with epoxy, the best and easest will be with a spray gun........true epoxies are 2 part with hardner.......so you won't find one in a srpay can, inless it's one of those tempurary custom filled cans, were you have to race home and spray it befor it gels and hardnes
