Hello all, 
I just read a little bit of Thommo's paint chipping problem.  I read about these silver pens and pencils.  Is there a specific brand to use.  Can u get them at any art store?  How much are they in terms of cost? 
Thanks, 
Happy modeling,

Hey Thommo, 
I checked into the pencils.  Found some at a local art supply store.  I haven't had the ability to try them yet.  They look like they'lll work though.  But I don't know about the pen.  I think it would.?.?.? 
Any one else know?
