Re: Rusty gas tank
Here's a picture of my hole. I don't really think there's much hope for it. It's a shame because the hood itself is in great shape.

Re: Rusty gas tank
Well after a few minutes of cruising the interwebs, I found this stuff MarineTex http://www.marinetex.com/Marine-Texfaqs.html#Anchor-Marine-44867 that is supposed to be great for fixing rusty holes in gas tanks, among other things. It is resistant to gas. I figure if I can seal it up with this stuff then coat the inside with the red kote I ordered I may be in business. One guy posted a review on Amazon saying that this stuff makes JB Weld look like denture cream, haha!
Worth a shot to save my hood.

Re: Rusty gas tank
Typically, when rust holes show up, a major portion of the tank bottom is also rusted. Almost rusted to the point of being holes. Waste of time and money trying to repair.
For the money expended on RedKote and Marine Tex you could purchase a clean solid tank and hood.

Re: Rusty gas tank
I have roughly $37 tied up so far. Please direct me to a hood/tank for $40 I will buy it right now. The cheapest I have found so far is $150 plus freight. I'm trying to contact a guy in AR but I havent been able to get in touch him yet. Not to mention the hood is in great shape I hate to toss out an original piece in good condition.

Re: Rusty gas tank
Keep in mind that any replacement tank is not likely to be perfect either. You might end up with one that has little or no rust but needs $100 worth of body work next to the light brackets. If you have one that is truly straight on the outside, I think it is worth an attempt at patching/sealing. If you are doing it yourself, you aren't out that much expense to try it. Just be very careful to exactly follow the directions for your sealer. If it fails, you can go back to looking for the perfect replacement.

I think Jim is right on. Notice too your rust holes are in the lowest part of the tank. I bet the rest of the bottom is more solid. You should be able to assess and tell.
If you are happy with the condition of the rest of the tank/hood, I would certainly try to save it.

Re: Rusty gas tank
I agree. It seems the weak spot is the low center section. I just read about some sealer at Autozone that is supposed to work really well too. My plan is to finish cleaning the bottom of the tank, apply the MarineTex to the bad areas, once dry I will seal over that with the sealer from Autozone, and then seal inside the tank with Red Kote. If that doesn't seal it I don't figure anything will.

Re: Rusty gas tank
Jason, If you're going to clean the rust on the inside with phosphoric acid (etch and prep, evaporust, etc.) or muriatic acid, I'd suggest you do that prior to applying the MarineTex unless the label clearly states that it is resistant to those acids.

Re: Rusty gas tank
I understand going with a new tank if it is a common hood. Some of us have holes in the tank on hoods that are a bit more rare... like the 1955 "No Holes" hood. I would be very interested to know how the repair works on this hood as I have found my tank to be just a little bit "porous" over this Winter. Started with a 1/4 tank of gas, and now it is bone dry!
Thanks and I'll keep watching for the results!

Re: Rusty gas tank
Mike,
Unless you find evidence of fuel dripping, consider evaporation as the culprit. BTDT. Ask Carl.

I'm just waiting for everything to get here. Once I get started, I'll take pictures as I go.

Thanks, Don. Yes, there is evidence of dripping along the lower right edge of the tank and also down the right side of the panel. I think it might be from a seam because the inside of the tank looks pretty good. I need to take my tank off and really clean it up and examine, but I have to get Merlin out of the garage first in order to start the teardown on Lewis!

Re: Rusty gas tank
Has anyone had any results from using Apple Cider Vinegar to remove rust from the inside of the tank before sealing with RedKote? I have seen many post on youtube and thinking about trying it myself.

Re: Rusty gas tank
Jason:
Take the tank to your local gas tank/radiator repair shop. They can most likely fix the holes and check for any other weak spots. Then they can mig weld it or tig weld the tank, re-clean, seal and do the pit filling and prime it for you. I had Grannys tank done 2 years ago .. cost me about 100 bucks Cdn .. or so .. and it is sealed with Red Kote, primed .. and oh yeah .. the found a mess of pin holes and fixed that right up... they are getting another tank to play with in a few months...
It is also a good safety idea. Red Kote and the other chemicals are not good for ones respiratory system .. ask me..
