We have had un heard of warm weather so I decided to pressure was the inside of the Commando tank. Outside is 100% dent free. It has pin holes through the bottom. Ive heard those replacement tanks are not that great & have heard mixed reviews on the coatings + how ya gonna clean it if I can't keep the cleaner in. I guess a used tank might be the answer then have it painted. What would you do
 
Even I know here is more than one type of Commando tank. Before they all start asking, better edit your post.
The Emco tanks have so far had a good reception.

Just pour a big load of Epoxy in It and when it hardens sand it off and paint it, sure it will weigh a fair bit and it is a bit dodgy and you will have to drain the tank after every use but that seems what most folk do when they want to sell a bike with a rusty tank.

You know who you are.!!!

I thought any good gas tank sealer would deal with pin holes. Assuming you remove the crud, follow the directions, etc.

Those emco tanks look a little different @ bottom rear corner to me. Might just be picture angle. I am worried if I poor in the cleaner that comes with those sealer kits it will make pin holes into gaping holes. & how to keep it in the tank to do it's thing. Can't afford a tank right now anyway so I guess swap meets hoping to find a deal.

Bead blast it and solder it up with a soldering iron. DO NOT use a torch! If it's really thin solder some brass shim stock over the holes. A radiator shop that deals with old time radiators should be able to do the job.
 
I have a fiberglas tank (and sidecovers) in excellent condition if you're interested. The tank has had absolutely no gasohol and would be an ideal candidate for the alky-proof coating.
 
Blast it clean. Lead solder. Pressure test, 3 psi, soap bubbles. dun. ride, enjoy.

Inside looks horrible. Prob will try if I cant find a tank for a reasonable price.

Keep the steel tank. I just pulled off my glass tank due to the ethanol fuel. Dont know about your area but I cant get straight gas around here.
Ethanol is death to fiberglass
 
get a big rubbermaid plastic tub and fill the whole thing, with the tank and the acid/cleaner/whatyouchose , then wait a few days. For a sealer, I used Caswells Dragon Blood, looks really cool , seems to be OK.( however have not had it in use a long time, your results may vary :? , and there are more steps in the process to be sure).

My daughter's boyfriend just cleaned the inside of his old Kawasaki tank with vinegar, a great mess of old rust came out. He put an inline filter to catch anything left.

Repair and keep the steel tank.

Have you had any experience with that gas tank renew company 850cmndo ??

I have. I had my Roadster and Interstate tanks done maybe five years ago. They did them with the existing paint in place. Blasted the inside of both and lined with a red product. One of the tanks had an old Creem application that appears to be gone. No complaints short of them getting a blob on one of the tanks exterior and that one will be repainted in the near future. So....ya takes yer chances. All said and done I'm ok with them. I'd certainly discuss the process with them.

Forgot to mention is cost 300.00 and change. If I remember correctly they gave me a break because of said blob.
 
Theres plenty of ' Acid Dip ' car body lighteners , Er STRIPP{ERS around . OR if you removed the paint & gunge , a Engine Shop's Engine Block Cleaning Tank ( Some are Alkaline ) might clean it , sparly ? new .

'
Theyre Acid Dipped .

Using the ' Heat Goes UP ' principal , ( Put the area worked on UNDER not ABOVE the Flame . Or use a TIG , any un famfisted barsteward should be capeable of doing a resonable job. Or Better .
 
I would like to save most of the original paint for now if possible. I called a place about repairing & coating it. The quoted me $575+. I think I will tape off the tank exposing only the bottom & blast it. Back in the day I worked @ a place where 1 of my duties was to solder chicken water float halves together. We used a soldering iron that was heated over a burner. Had a but tub of flux to dip it in once hot. I have been looking for this equipment with no luck. Not sure how else to get it hot enough with out putting a torch to it.

Judicious use of a torch will work fine, no drama, no ill effects. 40 years of metal working. :mrgreen:
