"Ed Gaddy"
We painted our Comet trailer with Supercoat. It is
a paint for metal buildings. You find it a building
supply store. It is white, very reflective, and will
reduce heating inside the trailer. It is flexible,
sticks well, and will seal cracks and leaks. We applied
it with rollers and brushes. The only drawback is that
it comes in 5 a gallon bucket.

Ed,
Can you be more specific about brand and product name. I looked around and
found stuff for sealing driveways. TIA.
