To properly impregnate the canvas tape you could use "creosote".... good luck finding some these days of environmental concerns... or "pine tar" which is used on the old wooden cross country skis..... again hardly what you would expect to find in a friendly Aussie hardware store......

OK... so what else is there.... that will be readily absorbed by the canvas.... not run and leave a mess at high temp...... stay soft and pliable.... and will last for at least 25 years....???

Any way of diluting silicone sealer to a semi liquid for the canvas to fully absorbe..?

I intend to use a flexible sticky rubber tape similar to what is used in windshield installations.... as we have serious rust potential here in salty Canada....

Suggestions welcomed...
