There are different grades of heat shrink. My buddy tried (as a test) the kind without the built-in adhesive. It did not hold up at all.@PJC , any update on how good the plastic dip is holding up on the bolts, I was gonna heat shrink mine ,but after some reading that seems like a bad idea, so gonna go with the dipping if it will hold up
We both switched to the marine grade with the built-in adhesive and it seems very durable. Time will tell how well it holds up.
I've used the plasti dip for years on steps, chains and some other stuff. It's not bad but my impression is the heat shrink will be more durable than the dip.
