Obviously the air circulation thing may have partially worked but did not prevent rust out. My thinking was that while you had the frame open for repair you could spray some type of anti rust material to the inside of the frame. After you make your repair what would it hurt to spray the expanding foam insulation into the remaining holes versus welding them shut. If some rust stop spray was applied to the inside of the frame and filled with foam , you eliminate the air /moisture factors from the inside out rust problem. Just a thought.
I have seriously considered the spray foam idea!!!
I plan on putting some good size drain holes in the bottom of the frame after getting it all welded up. I also considered the rust encapsulate r but the scale on the inside of the frame is quite bad I dont think it would help in the areas I cant get to.
Thanks for the link i checked it out it I have a friend who goes every now an again if he goes I might tag along.
The weather has been pretty good again the past few days so ill b getting back to work on it
