I feel your pain......I made a handbrake gaiter a couple of years ago https://www.aulro.com/afvb/series-la...ml#post2440711
I found a supplier for butyl rubber tape https://www.aulro.com/afvb/series-la...4=#post2414520 problem is the link is a bit out of date. They were in Dandenong and I could probably find them again if anyone wants some, heavy stuff to freight though....
I used glazing silicon on one of my Land Rovers but now I have the tape I'll probably use that in future.
Best of luck with the roadworthy.
