Worthington Cylinders Coated?

Somebody finally responded to my wanted ad and I just picked up some 30lb Worthington aluminum tanks for my trailer for $50!!! Thought that was a great deal. These came off a 74 and have been updated with the OPD valves. Does anybody know if the original tanks were coated with anything? I'm debating if I should polish or just leave them alone. It almost looks like they were coated with something. Thanks!

I don't believe that Airstream Plasticoated the tanks installed on trailers. When I had my coach polished and Plasticoated at P&S Trailer Service, they polished the tanks but recommended against Plasticoating them as the coating would be very easily damaged when refilling the tanks resulting in significantly reduced life expectancy of the Plasticoat. My tanks still look nice even after being out in the weather for eight years with no Plasticoat.

Good luck with your investigation!

Airstream has never applied any type coating on aluminum bottles.

The finish wasn't a plasticote. It looked more like a light anodized finish from the Worthington Factory. I was cleaning the tanks up and went right through the finish. Looks like I'm going to polish.

brushed aluminum tanks

is the finish like a brushed finish? I am looking to buy alum tanks and polish them for my trailer. Looking at the ones for sale ar West Marine, they have a "brushed" finish and I'm not sure if they can be polished.....any advice?

My tanks were a little rough, but they did polish nicely. I bought mine from VTS. They are the Worthington brand.

My advice is shop around. The largest tank West Marine lists is 20 lb for $299.99.

Vintage Trailer Supply has larger tanks, 30 and 40, in addition to the 20 and smaller ones. For comparison, a 20 lb tank at VTS is $147.99.

Both are Worthington Aluminum tanks.

I don't know about the tanks, but something to think about when you change to a 40 Gal. tank: While waiting for the Ferry at Horseshoe bay near Vancouver, BC. I noticed a Ferry worker eyeballing my 30 Gal propane tank and she was on the cell phone. I walked over to her vehicle and asked her if there was a problem and she said: "Is that a 40 Gal. propane tank?" and I replied no, it is a 30 Gal. I was told that if it had been a 40 Gal. I would not have been allowed on the Ferry. Just a point of interest.

30 vs 40 pounds, not gallons. A 40 pound tank holds a little over 9 gallons.

Interesting about the perceived problem with the larger tanks on the ferry, though.

what is the difference between the aluminum forklift tanks and our rv style? I cannot find any used alumnium ones around here except for the forklift type.

Forklift tanks deliver propane in a liquid state to the forklift. RV tanks deliver propane as a gas to the devices.

It's the pickup location inside the tank that differs between the two.

The liquid design delivers it to the point immediately before it is allowed to change into a gas, useful to have more fuel close by to rev up engines without (much) lag. Often there is a heater that boils it before it is metered into the engine to keep the line from super-chilling from the phase change.
