Should I seal the gas tank after molasses?

I am planing on treating my 49 Buick gas tank with mol***es as the inside is very rusty. Is it necessary to seal the inside of the tank after word, or should I leave it un treated.

 

Mole ***es?

Why not vat the tank? HRP

 

I've never been a fan of the so-called tank sealers. They fail way too frequently, and when they do you have a real mess on your hands. If it's not leaking then clean it, fill with good fuel and go...

 

I prefer bare steel in a gas tank, but there are alot of coated ones. If it leaks after, seal it.

 

Sounds like you're in the market for a new tank............two things ya don't go half ***ed on, on a build: one is the brakes, the other is the fuel tank! Picture how thin the tank is now, and how much a full tank of fuel weights? Add in a car load of family or friends and 16-18 gallons of fuel & headed out for a fun time................oh ****!

With the amount of corn alcohol in most fuels today, most of those tank " sealers'' are 'bout as worthless as muel ***!

I would leave it unsealed. I had my 58 brookwood gas tank acid Diped ( local radiator shop ) years ago then they put there tank sealer in and coated it. All there (tank sealer) washed off with the gas and I had purple fuel for months.

And most likely clogged fuel filters.

Avoid the tank sealers,we were on our way to the NSRA nationals back in 1988 and spent quiet a bit of time on the side of the road with a friend that had used a tank sealer and it started letting go.

I believe the finial count was 11 before he got back home,needless to say the tank came out as soon as he got home. HRP

 

I would also stay away from gas tank sealers. Years ago with the gas they were selling, sealers were just OK, not great. Now with the 10 % ethanol, I have heard nothing but complaints. In my area they are now talking 15% ethanol so who knows what gunk you will end up with in your tank.

 

Here is the deal on tank sealers, you get what you pay for. I got a pair of tanks now on an off topic for the board vehicle that the previous owner sealed and the sealer is peeling off, I am dealing with it but it would be a pain to deal with on the larger scale of an automotive tank.

The deal is you buy a good quality name brand sealer and one that is alcohol resistant. Moroso I belioeve makes an alcohol tankl sealer that is very durable.

I would not mol***es soak the inside of the tank, you will never ever get the mol***es out, they actually make a tank cleaner that will get the rust out and rinse out after you are done with the job, or you could find a radiator shop or old machine shop that still hot tanks. I have my tanks hot tanked, they come out clean and it still runs me 20 bucks just like it has about forever. Last one ran me 35 because they found 3 leakes that they silver soldered.

Wellthat was a mouthfull, sorry to take up all your time on that one.

 

Even if you fill it wil oil and gas, it will still rust after etching it with mol ***es or vinegar or acid. Without some sort of neutralizer it'll just keep on rusting. Acids won't touch oil or gas.

I have used the Kreem (sp?) tank sealer on many motorcycle tanks and it works. Like many things, if done improperly, they will not hold up.
