    I see you haven't got a reply yet. I use my favourite rad shop for a complete dunk. I also use pea gravel sprayed  with wd 40 and shake the shit out of it to loosen up the rust.

    Whatever method you use to clean out the majority of the rust, the key thing to do is seal the inside of the gas tank afterwards. A lot of the guys are using Caswell's sealant now(find it on their website) . I have used it successfully on about 5 tanks now and highly recommend it. It is a 2-part epoxy that is unaffected by ethanol. They do have a Canadian distributor.

    Ive had good luck with hydrochloric acid 32%. You can also use a 23% toilet bowl cleaner. It depends how bad the rust is as far as how long you leave it in the tank. Then rinse rinse rinse, let dry and i use the creme liner. Never had any problems.

    I would not recommend the use of the Kreem brand of sealant. I've read a lot of complaints about ethanol in the gasoline causing it to come apart and cause all kinds of problems. Caswell's is recommended.

    Hello
    The main thing to remember when you are sealing tanks, is that you have to have all of the old gas and oils out of the tank before you seal it with most sealers. If you can not be 100% sure that all of the oils are out of the inside of the tank just clean the rust out with the rust removers like Por-15 has, (they call it metal ready) it will leave a light zinc coating on the inside of the tank, then flush with gas, and fill it with gas, do not seal it, just run it that way and keep an eye on it. Caswell's sealer works on a different premise than the other sealers because it forms it's own structure (like fiberglass) inside the tank so it does not need to bond the same way as the Kreem and and Por-15 does. The only thing I would be afraid of with it is that over time you could get condensation between the liner and metal tank, then it will rust. This may not happen for a while but if the bike is not stored in a heated area in the winter it could happen. The other thing to remember about all of these sealers is that they claim they  will fix cracks, they  won't in a stressed mount area, rust holes yes, but not stress cracks. Tanks like the ones from the first year oil in frame Triumph and BSA's will stress crack forever unless they have a tie-bar mount put on the bottom of the tank like the later tanks did. I repair tanks for a living and that is why I know this. When I seal a tank I have the entire tank stripped clean to the bare metal inside and out, then I can do any repairs, pressure test it and then prep for sealing before the tank is repainted. A lot of people paint the tank first then the want to seal it and the that is when the problems start. Talk to you later.

    I have heard people mention using Muriatic Acid to clean out an old tank...does anyone know where it can be purchased? 

    I too have a tank that I wish to clean out but I am debating on sealing it or just filling it with gas as the pervious poster mentioned...

    Hey there! I am new here, and this is one of my first questions as well. Thnx for the info. Does anyone know of anyone in Edmonton who does tanks?? I have a previously lined tank that is peeling like a redhead after Mexico! How do I get that out first??

    PS.. the outside of the tank is in good condition.

    Hi Dave
    Por-15 makes a stripper that is designed to remove old sealers, if you Google Por-15 it will take you to there website and it explains the process and should give the info on your closest Canadian suppler. Talk to you later.

    Muriatic acid is used in the swimming pool business to clean up cement.  Available from Canadian Tire and of course, pool stores.
