I'm building my latest contraption. Its a large metal plenum for directing
the air from an air blast sprayer down onto three rows of strawberries.
Think of an air duct for heating with three registers, only use a forty
horse power fan and very small openings.

I made the whole plenum out of sheets of 1/8" steel, and 1/8" round tubing
of different sizes. Its all tack welded together now. I'm going to finish
welding for strength this afternoon. I'll stitch weld with a three inch or
so gap between every one inch of weld.

I'll have yards and yard of places where the metal meets that I need to
seal. It needs to hold up to vibration and high air pressure. And be
paintable. What would you use?

What more would you want??

and you can buy it at Home Depot too!
We use buckets of a similar product where I work. The stuff goes on with a
1" paint brush, it has the consistency of pudding. It stays flexible and you
can paint over it once it dries. It dries completely overnight.
