I cleaned it with TSP, caulked and filled the holes ,primed it with an oil based primer and painted 2 coats of good paint.  

I have never experienced oil furnaces (or whatever they are called) either.  

As for stocks, some of my personal favorites are oil companies, because there are some that have tracked really closely with the price of crude for years and years, so they're pretty predictable.

The Lemon Ginger one is great too.

With just $15, you can buy a big old bottle of reconstituted lemon juice, a squirt bottle, and a canvas bag.

My maintenance was like ... oil changes, brakes and tires.

While oil prices may go up in the short term, the increase will be capped I think due to massive shale capacity and increased alternatives.

Yeah, I have plenty of oil stocks

Markets are dynamics, not static. "...oil is the main driver of the economy.

But low sell high Yes, single stocks first mostly oil, banks and airlines.
