I took a look inside the tank of our RD350 and saw this.... Are there any good places in southern ontario that can fix this?

Steve, That stuff works great! Do you suggest just filling up the whole tank with it?

Is that really rust, or could it be varnish? I had a tank that I tried to de-rust for quite a while, and finally figured out the crusty brown stuff was varnish. Lacquer thinner dissolved it, and there was no rust underneath the varnish.

Jim...thats a good question.
The bike only has 599miles on it and was stored indoors it's entire life with an empty tank. So it's not like it was really exposed to the elements too much to cause that much rust...

Well, empty would probably mean it's not varnish. Mine had been put away with fuel in the tank, and over many years it evaporated and left the varnish.

Dom16 is a Canadian based version of por15 at 60% the price. One time sealer right over top of said rust. Seals and uses the rust as a bonding agent. I have not used it in a tank yet but know people who have. I have used it for other purposes and love it

From what I've read, Caswell's phenol novolac epoxy is a safer bet than POR-15 if you really need a sealer.

As for sealing rust under the coating Mitch, sure let it rust out from inside and you will see the holes later. And as for shellac, excellent point. I always fill it with gas and let it sit for a day or so. That loosens anything as a rule. After drying it outside, I then fill the tank with the evaporust. Then let it work for a couple of days. Chrome and stainless stuff with light rust clean up in hours. I used to buy it, a gallon at a time for 28 bucks. Now I can get the 5 gal size for 75 or 80 bucks. You can reuse it many times. Just pour it back through a bit of cheese cloth or a paper towel. If you only get a gallon to try it, you just have to be patient and rotate the tank so it gets everywhere. A few more days are needed that way too. There are a few products claiming to get rid of rust and most work fairly good. This stuff is the best I have used ever. NO, I don't own stock in the co.

Man, that bonds like crazy..didn't come off your hide even after sliding along the asphalt track

The inside of the km looked like that. I put a couple hand fulls of nuts and bolts in the tank and rattle it around to loosen it up, bought metal restore at crappy tire, filled the tank with it, let it sit a day and it cleaned up real nice. I then lined it with kreem brand liner, ethanal safe, turned out pretty darn good. Rust restore is 35 bucks for the gal size same results as evaporust.

It takes a bit longer, but just cleaning strength white vinegar will clear out rust. And much cheaper.

And you just dump it out with no problems. Did my KZ tank with it , the rust wasn't as bad as your tank about 50% less from the pic. I filled it with vinegar and let it sit for a week, rinsed with water then some WD-40 then filled it with gas and has been great.

My method of choice is electrolysis followed by the Caswell 2-part epoxy tank liner.
Works like a charm and the only real cost is the Caswell kit. I've found it's enough for two tanks of this size and vintage.
Cheers, N.
