[R-390] Some chassis marking tips

[Perry Sandeen via R-390]

List,
 
One technique I used when working on equipment is to
annotate inside the chassis with the fine tip Sharpie.  It cleans off fairly easily with most common
solvents.
 
Before you remove either the PTO or BFO if you put some nail
polish (a color mama doesn’t want anymore) one the shaft where it exits the
module it will hold it in place very nicely. After re-assembly a little acetone
or nail polish remover will take it off.
