Hi Stew

I am pondering the same problem... I have saved all kind of little Pieces of that elusive canvas tape........ but for the sake of protecting from furhter rust I intned to use a non-porous material.......

Electrical shops ... the ones selling to "real" electricians stock a pure rubber tape in 1 and 1 1/2 inch tape .... very soft... strechy .... can be bent to curve the angle iron you are referring to.

However it may be too narrow for some application....... this source I have not explored yet but I have been told is readily available.

Winshield installers ... automotive glass shops have a special .... various width... very sticky rubber tape which they use to install glass in window channels.... basically glues ove the edge and wraps up on both the iside and outside of the glass and keeps the metal from having any contact with the glass itself..... also seals out any water. They should be able to sell you a roll.

Don Dingwall, who is in the same process , had considered using some surplus thin webbing he saw in a surplus store and soak it in a diluted tar solution........ sounds messy to me.

Curious to see what other suggestions you will receive.....
