Filling a Stanchion?
I am in the process of re-bedding my stanchion bases and adding backing plates. Upon removing the stanchion bases, I notice lots of rot and gunk buildup under the bases. I believe this is due to water traveling down the inside of the hollow stanchion tube (penetrating tube holes where lifelines pass thru), and then sitting inside the stanchion bases where it contacts the deck, thereby eventually rotting/penetrating the bolt holes from inside the base! Any suggestions on how to stop this from happening when I reinstall the bases and stanchions? Possibly plug the stanchion tube up near the lower lifeline holes...but with what? Could I fill the stanchions with spray foam? Suggestions?
