    Rust-proofing tanks?

    I recently bougt an SRV250 knowing there was a rust hole in the tank. Had this fixed & painted - looked great! Two or three weeks later there's a bubble in the paint near the repair - turns out it's more rust holes.

    I've decided to get a second-hand tank from a wrecker in Japan. Looks in good nick and will cost about the same as another - possibly ill advised - repair.

    Shoud I rust-proof this "new" tank before fitting it and, if so, what should I use?

    Thanks.

    Hey there, i've had this same problem on 2 of my previous bikes. what you need is a POR-15 motorcycle tank repair kit if you want to repair the tank you have. that cost me $80 from the paint shop here in chch. if you wanted to buy a new tank without any rust in it than i think you might need the kit if you want to rust proof it (or just certain solutions from that kit, i'm not sure you'd have to check from the paint shop but they do sell the bottles seperately)

    if you want to see which shops sell the por15 products than click under the distributers tab

    Note: if you use this on your tank make sure you remove EVERYTHING from your tank that can be unbolted/unscrewed off, the marine clean solution will eat anything rubber and ruin any paint it stays on for too long and the tank sealer will stick to ANYTHING it comes in contact with for more than a couple of seconds and will seal any 1mm holes it comes in contact with and its near impossible to get off. also the anti rust solution will eat away at the rust in the tank however if the rust is all the way through the metal than presto you have a new hole in your tank lol so try and clean up as much of the exterior rust you can and if its that bad be prepared to weld some bigish holes up (dont worry if it makes small holes the tank sealer will take care of those). This process takes a good 3 days to complete and gives you a sore arm because you have to constantly slosh the solution around every half hour or so.

    I hope that helps, the kit comes with a step by step instruction sheet aswell.

    Goodluck!!

    POR 15, the only way to go, and if I can use it, anyone can

    just be bloody careful what you use and follow the instructions well.My mate just bought a 2006 bike when he rode it a few weeks later it had a fuel miss.When he looked in fuel tank it had sealer floating around because some numb nuts lost the fuel pump seal and used some red sealer.But the other big problem was the sealer some one had put in didnt adhere to the inside and was falling off in huge strips its been a huge job to remove lucky none of this shit got past fuel screen.By the way this crap was gloss black. the best policy is to leave the tank full when not in use so condensation doesnt form

    OOOPS wrong thread. And I though there would be a few good hints on how to build a better tank
