I have a large h-post that has rusted out voids beneath the horizontal crossbar. Since it's basically just a hollow steel pipe, I was thinking of digging out as much rust as possible, hitting it with ospho, spraying some expanding foam sealer inside the pipe, then applying some MarineTex to plug the hole. Any flaws in this plan?
