I put Denso tape around mine when I swapped from six to four leaf springs as part of my Plus 8 rebuild. I sprayed the new springs with motorcycle chain lubricant first. I've only done about 200 miles since, but it is very quiet and non- creaky and should stay that way. You are very welcome to my "tool" which is two strips of mild steel bolted loosely together and used in conjunction with a crowbar I already had. If you mail me directly, I can send you a photo. Similarly, I have some Denso tape left which you can have if we can work out an economic way of getting it to you. I can't see me using it again in a hurry - very sticky stuff.
