what type of paint do I use on my 100 gal above ground propane tank
I know it needs to be white but does it matter if its a latex or oil base paint
I would recommend the Rustoleum 9800 series Urethane mastic. It will cover old paint well if everything is cleaned properly. In CA the tanks don't have to be white. I like the Dunes Tan if it's still available. It dries glossy, but dust and weather will take care of that. In a garden setting, you'll find that it will almost disappear. Use a 3"or 4" std diameter roller. Mix 1/2 the paint with 1/2 the activator and put it on thick. It's a catalytic curing reaction, so it will get very hard as it cures. Do a good job and you'll never have to paint it again. I'd clean with Simple Green and Scotchbrite first and let it dry well. I painted a 2000 gallon diesel tank and it's containment tub with this exact paint. When I got the tank it was painted with aluminum colored paint. After I was done it only looked about half as big as it did in silver.
