Detail Masking Ideas

[JOE FULTON <piper_pa20@xxxxxxxxxxx>]

I'm trying to touch up (actually re-spray) the silver
paint on 73 Javelin tail lights.  I also want to
recolor some AMC wheel covers.  

I'm looking for detail masking ideas for spray
painting that actually work.  I have tried fine line
tape and regular masking tape.  I have tried a masking
medium (flexible membrane) used my model makers.  I
had pretty good success with the latter product but I
want something that will work PERFECTLY.  Pretty good
is not good enough.

Does anyone know what the factory used to mask these
items for painting?
