Got the tank unclogged, 81 honda cm400. was sitting since '84, all clogged up with tarnish + rust. unclogged petcock + tank with lauquer thinner soaking, got seaform now. My ??? is how do I use it to clean tank some more. I got 2 pint cans, should I mix it with anything or just put gas and seafoam in. I plan to reline the tank, any help is greatly needed.
