hi. when welding a bit of sheet/pannel perpendicular to another, i know its best to fold a bit of an edge (10mm ish) to aid stiffnes and reduce warping, but then its like a lap joint, coss then you cant paint/protect the inside faces from rust,
so what do i do, is ther some kind of paint that you can weld through, on do i just fully seam weld with no gaps then use some kind of sealant, so that no moisture can get in
