I've recently bought (3) 5 gallon jerry cans from craigslist ($15 total!) and they look pretty disheveled. They are functionally sound, Just need some cleaning, painting and new gaskets. Can anyone give me any tips to clean and paint them? thanks
Assuming they are the older metal type, the interior rust and crud can be cleaned out with Muratic Acid (available at swimming pool supply place). Be careful not to spill it on concrete as it will eat it up. Twin City Surplus has the spouts and gaskets. For the exterior, sand and repaint to your liking.
i hasve a number of jerrry cans and to keep the insides clean and happy i annually take the empty can and pour in about 1/2 qt of motor oil. Shaken shake and turn then let it sit flat, then on side,m ratating, etc. and over a few days give the insides a good coating and soaking. then fully drain the oil into the next can and repeat. Seems to work very well.
Do NOT get muratic acid near or on anything zinc plated!!! it will create a gas that will suffocate and possibly kill you. As for cleaning you could go and get some ceramic tumbling media for deburring metal parts in a Tumbler. Harbor freight http://www.harborfreight.com/1-1-2-half-inch-x-7-16-inch-large-ceramic-polishing-media-97029.html will possibly have this as will MSC or any industrial supply place. put the media in the can after cleanig it out with mineral spirits. add some water and shake them for a while. employ your freinds with beer and pizza to help.
I'm not sure if it's zinc plated or not, but I'm not about to find out haha. The motor oil and mineral spirits sound like a good idea. Ono of the cans the guy gave me had rocks and dirt in it, no joke. I asked him why and he couldn't tell me. I was like "whatever" *hand $5 over and leave*. Also, one of the cans had old gas in it, about half full. Any ideas of how to legally and safely get rid of it?
So as far as storage, what would you recommend? I don't really want 120 more pounds on my roof rack, it would mess up Center of Gravity and look awkward. I would probably go with the rear bumper option. Would it be possible to make something to go into a hitch reciever?
I'm sure they're fine with fuel in them. It's when you have NOTHING in them when you want to store them open. People don't realize it's not a plastic gas tank and they condensate inside which leads to the rust. I'd use them like normal however find a good screen to put between the tank and whatever you're filling. Maybe buy a funnel with one so you clean out the tank and can use them at the same time.
Or fill it with rocks and bang it around and rinse it out a lot.
