Hi guy's...before covering,i think it was a good thing to do....with different way to protect the inside of all steel tube on frame...a lot of guy's here in Québec use tube seal in restoration like old cub...they make a little hole on each tube and shoot the tubeseal and close the hole with (rivet or welding)

Do you (kitfox builder) ever use that on a kitfox...do you think Master John Mcbean use that ..

Thank's
