I would not spray the entire inside of the tank. The only likely leak prone areas are where it has been welded. Is that where it's been leaking? Personally I would try flux and Silver solder. It comes ina little tube ready to use and just need a small torch. Other than that 5200 , jb weld or something like that will last a while... on the outside only though...

Tspringer, how did the Microseal work? Any tips you would care to share?

I've recently discovered the joys of Gflex and am now a believer. It bonds to everything and is flexible enough to be tough and not brittle. I just had to reattach a fiberglass sheet to my polyethylene holding tank and Gflex did it beautifully. Polyethylene is really hard to bond to. I also just bonded some stainless steel with it and it bonded so well that I could not lift an edge with a screwdriver trying my best. It it just that tenacious.

If it was my tank, I would clean, dry and prep the surface, throw some Gflex on it, and know it would be good to go. Super easy.

I also agree with the post that says don't worry about it, but then again, any leak of any size can just drive a sailor crazy. It's sort of the broken window effect. Let a small leak go, and then...

Good luck on the refit.

I agree that G-Glex is a terrific product. I talked to Gougeon about it a while back and they advised it would probably work with the provision that the interior surface be prepped by careful cleaning - and here is the clincher - they recommended that the surface be abraded after the mixture was applied but before it started to kick - to prevent oxygen from affecting the abraded surface (yes, even on stainless steel). The Microseal sounds like it would be an easier, more thorough application though.

I did use the microseal and it appears to have worked well. I dried out the tank (this took a week or so) and then squirted the stuff in as per their instructions.

When I went back to using the tank, no leaks. That was a few months ago and still no leaks. Very easy to use.
