Believe me if I could easily and conveniently keep them
dry I would do that.
ANY of my previous LP covers did not really keep water
out of the tray where the tanks sit. The bottom ring on the
tanks and the tray itself seems to be the most prone to
rusting. Every 2 or 3 years I get out the black rustoleum
for the tray and white for the tanks. It's just part
I took a couple feet of 1/4 inch ID rubber hose (industrial
air hose or automotive fuel line will work) and carefully
slit it long ways with a sharp box knife. Then I placed this
slit hose on the bottom ring on my LP tanks.
This really cuts down on the scuffing of the paint in the
tray and the bottom of the rings so I don't have to paint
quite as often but the hose holds water so the ring
stays wet longer after a rain.
EVERYTHING is a trade off.......
Also, there is a commercial HUGE LP filling station a few
miles from my home. They re-fill my tanks so I also paint
them when they need it. It saves me a few bucks each
time vs trading them in at Wal-mart or Sams or Lowes
or Home Depot. BUT if they were really bad shape, I'd
trade them in and pick a full tank that looked good.
