ive been using this since i got my bike..its good stuff..but the side effect of its protection is that dust sticks to the protective coating, therfore more washing ..great on wheels though for the same reasons
i guess you cant spray it on the exhaust since it will just burn off, right?
the exhaust takes the brunt of the salt water road spray.
i could spray it in the axles too, they have corrosion from riding in the rain, even though i occasionally clean them with wd-40
dont know about better ..different, the closest stuff i can think of is what we call "salesmans slime" you know the oily sticky pollish you find sprayed all over second hand car dashboards
