I don't think foam is the right thing, especially with saltwater.Wind Chime wrote:I was at the boat yesterday doing brake maintenance, and was thinking about putting expanding foam inside the steel trailer tounge.
We rebuilt our 2000 steel factory trailer a few years ago and replaced the steel tonge tube. The tonge gets submerged in salt water during most launchings and even though I insert the hose inside the tube to rinse, its bare steel inside so just a matter is time.
Do ya think expanding foam will help keep the salt water out of the tube and away for the bare steel, or will the foam just get saturated with salt water and make the eventual erosion worse?
