El_Retardo Posted March 22, 2019 Share Posted March 22, 2019 Right I'm sure most of you are going to say get it welded up propperly but are fuel tank sealers any good? I have a heavily modified tank so cant just swap it. at 2 points fuel is seaping through. I left fuel in for 2 weeks and it's not dripping just moist around the welds and really want to get the bike finished, is it worth using a sealer? Quote Link to comment
Dezza Posted March 23, 2019 Share Posted March 23, 2019 The general consensus on here is that POR 15 is the best tank sealant (question arises regularly, including from me in the past). I lined a small tank with it last year and it works well. Buy the kit with the primer and all the preparation chemicals. It's not cheap but decent stuff that works properly rarely is It may be prudent to examine in detail why your tank is leaking as you may have to have some holes braised first after rust removal before lining.

Blower1 Posted March 23, 2019 Share Posted March 23, 2019 Fertan Tapox TX 10 is also good tank sealer. I have used it successfully in two steel tanks which were leaking before. Quote Link to comment

Inside of the tank is practically rust free it's just in 2 spots where new metal has been welded in to make it fit that it's seeping. Yes I can take it back but he is that bloody slow it will probably be a year before I get it back. Quote Link to comment
Gixer1460 Posted March 23, 2019 Share Posted March 23, 2019 Braze over - use someone local or DIY solder could be an option? Quote Link to comment

philwright Posted March 24, 2019 Share Posted March 24, 2019 I have used Caswell sealant in the past on carbon fibre tanks with good results, quite expensive but i spose you gets what you pays for. Quote Link to comment
nokturnal Posted April 4, 2019 Share Posted April 4, 2019 +1 for POR15. Used it in several tanks. Had caswell fail. I would solder the holes first and then coat. Then forget about it forever... Quote Link to comment
