I work on/build allot of dampers (mostly Ohlins, but some Fox, too), protection of the rod and seals greatly extends the life of the unit. Boots have earned a bad reputation over the years, and with good reason. When boots are zip tied on they don't let anything that has made its way in an easy way to get out. It's mostly water and silt/sand, which builds up in there, and wreacks havoc. A loose boot or metal/plastic tube shield is the proper way, as it lets stuff back out. If the boot is tight, I cut a slit in it so it can drape over the shock body and allow stuuf to escape. It also allows inspection and a quick spray out should it be required. IME
