Make the bigger diam. shrink about 3" long this provides excellent support and sealling for the splice.


I use the Rosin core and the HD heat shrink (with the glue inside) but I had never thought of doing it as a two layer setup, sounds good, thanks.


My, what a steep learning curve. Erik II#5155
