[OM] Introduction and lens mount question re. danger to OM4 reset button

Hello list members,
I've just joined the list, although I've been lurking on the online archives 
for quite some time now (I've even bought a few items from list members).

First of all, a brief "OM history" and about myself:
I bought my first real camera in the early 1980's, an OM10 with MIJ 50 f1.8.
Pretty soon after that I got a cheap used Vivitar 28 f2.8 (I now know made by 
Komine, and actually a pretty decent lens), a weird Soligor 45-135 f3.5
zoom (massive beast), and some time after that a Zuiko 200 f4.

For many years this was my whole kit, until a year or two ago I discovered 
this list and *bay.  I've now got about 7 bodies and 25 lenses, and 
counting...  This brings me to my question:  among my most recent 
acquisitions is a Vivitar Series 1 90-180 f4.5 flat field zoom (in excellent 
condition, only a scratch or two on the corners of tripod mount to distiguish 
from new).  This lens unfortunately has 4 screws holding the mount on, at
12, 3, 6, and 9 o'clock positions, which as far as I can tell is exactly the 
same configuration as the "dangerous" Tamron adaptall mounts re. shearing off 
the little reset button on the OM4 lens mount.  My problem is that my normal
"serious" photo kit includes an OM4 and an OM2N and a bunch of lenses,
so that if I include the 90-180 zoom in my bag I'm in danger of accidentally 
mounting it on the OM4.  The lens is nice and somewhat rare, so I certainly 
wouldn't want to use the epoxy fix that is fine on the adaptall mounts, since 
at some point it may be necessary to open the lens up from the back to get at 
the aperture for eg.  So I'm looking for suggestions:  what could I use to 
fill the screw hole on the lens that will not easily fall out, will be smooth 
and slippery enough for the little button to slide over it easily, and then 
also be readily removable (solvent?) if it becomes necessary to service the 
lens?
