About every third tank I use 4 oz. just to maintain. No problems so far.
I am in the process of derusting the tank of a honda cb 125. I am using E Vap O Rust which I got a Harbor Freight.
So far I am impressed with the results, but I need more to completely fill the tank. I bought a bag of nuts to swish around on the inside to polish off the residual with a little friction.
It seems much safer than the acid method and appears to be kicking butt so far! There are no toxins or caustics involved so the kids and dogs need not be poisoned or burned. Or more likely me.
Anyway, unless you are satisfied that all the rust is out of the tank, the sea foam is of no use for rust, either in the tank or the lines or carbs.
