I want to follow Martin's lead and pack the volume between the seal and dust cover with a silicone-based grease. Bike has 27k miles, no idea of the history before 14k or so. No records indicating any maintenance on them. Seem to be working quite well. No leaks, no pitting on the tubes. Not ridden in a dusty environment. Tubes are wiped down after every warm weather ride (Georgia bugs, nasty).
My covers on my 92 75 RT look like this:

and while I am at it, another question. Some covers look like this:

Which bricks have those?
