Tank repair

[jwebfournow]

Hello all!


        Have been reading the posts on tank repairs.....was wondering if anyone has actually cut out a section and replaced it with fresh metal, then used POR-15 to seal the tank after all the metal work has been done. My tank has a few  pin holes on the bottom right side outer and inner sides, the left side has a few pin holes on the inner side but the outer has holes the biggest being about a quarter inch in  length by an eighth wide.  and the others follow a trail from there spaced apart. I'm wondering if the tank could  be repaired using jb weld then POR-15 or would it be better to just cut out all the bad and replace with fresh metal. The rest of the tank looks pretty good no dents just some fading on the top portion of the tank. Or should I be on the lookout for a good tank. I do have a mig welder by the way, and the tank has not had gas in it for at least 20 yrs. Just never welded on a tank before. Any suggestions would be welcomed. Oh yes by the way the holes are in the typical low spot of the tank. No where else. Anyone have a good tank for a reasonable price.

Look no further grasshopper.  You come to good place for info.

What you should do is first, sand the tank down to bare metal.  Then apply fiberglass matting all the way along the bottom edges of the tank.  This should be a strip of matting about 2" wide and long enough to start about an inch rear of the rear lowest corner and span all the way until it is about an inch or two forward of the forward lowest corner.  Do this on both the inside and the outside skins of the tank.  Then just fill in with bottom outside area with bondo for that "seamless look".

Or you could just jb weld it. It sets up very smooth, and a bit of sanding and its it's own bondo. Mines been that way for two years with no problems.

then there is a product, not new, but i just discovered it, called "Seal-All". it's a clear liquid, fuel & solvent proof, that sets up hard but flexable.  neat stuff.  might make a good coating for intake boots too..

Ever tried boiling the boots in wintergreen oil and water? It's all the rage for the sohc4 folks in the honda realm. Takes em from being rock freakin hard to supple, pliable, and brand new condition. Apparently, too long of a treatment and they swell up like balloons. I think a vision boot given a good soak would swell just enough to seal up any of those surface cracks and could fix actual through and through cracks pretty well, especially with a coat of sealer.

Thread tangent...

Inanecathode, when I read what you posted about wintergreen oil, I kinda rolled my eyes, but I googled "honda wintergreen oil" and apparently there is something to this...

Also Peanut oil is said to be fantastic for restoring faded black plastic.  i use a product called 'back to black' & it works pretty good too...

Similarly,I had heard about plant glycerin on rubber, keeping it supple, too... Think, Sidewalls of tires during winter storage, etc...

Funk, I just repaired a Norton Interstate fuel tank for a friend. I cut the bottom panels out, they rust at the weld seam just like the Yamaha tanks do. I then had it blasted inside and out, now all rust is gone. I made repairs with new sheet metal and tig welded it all back together.
Then treated it to a coat of Caswell sealer then off to the painter, this was not a cheep repair, but this tank now looks new inside and out.
