Next step will be taking a wire wheel to all the flaky paint surfaces and then prime and paint the entire frame. We live somewhat near the coast and it's almost always humid here in coastal southeast Texas. It would be prudent to paint any exposed metal to prevent any future corrosion.
Oh yeah and we will also assess the frame for any rigidity issues. This frame is kinda more flexible and twisty than I like. We will be welding in some reinforcements to prevent the flexing and twisting. We will also be welding on support members to mount the perimeter of the framing on. This will allow us to build to the 8'6" maximum legal width.
