This looks a little cleaner, thus my original question:-)  Will garden variety heat shrink work in this application?

Bruce Turrentine recommends the race car solution, which is to run a bead of silicone around the bolt in a spiral pattern prior to inserting the bolt.

Tracy, the intrepid experimenter, thought this was too "hit or miss" and decided to develop something more predictable.  He has replaced all his bolts and put heat shrink tubing around the bolt instead of silicone.  We'll keep you posted on how well this works.<<<<
