HP-67 Shiny Spot on Face

I recently got an HP-67. One cosmetic problem it has is a shiny spot on the front face between the "E" key and the "SST" key. A couple pictures are here:



Has some outer finish worn off in this area? Is there any way to restore the matte finish to this area?

Does this work?


Some possible solutions: http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv019.cgi?read=160724#160724

Search the archives for more posts from Geoff on classic restoration. Tons of good material there. Someday, it might even become a book ;-)


Thanks, works great!

Geoff, give us a IBAN for the reservation...what's about the last chapter?
I'll give you the GPS point of my home, drop me a prewiev please when you fly on this area :)

Thanks for the pointer! I was not using the right search terms.

Looks like I may have made it worse by using 409 :(

At least the label did not come off. I'll try spraying with matte lacquer once I have it apart to fix the card reader.

Without a doubt. You're lucky the white lettering didn't melt away.

Check out the ingredients: http://www.biosci.ohio-state.edu/~safety/MSDS/FORMULA%20409%20CLEANER.htm


Here are a couple pictures of the face after disassembling, cleaning and spraying with Matte Clear Lacquer paint. Not perfect, but better!

Also got the card reader working while apart.
Thanks for help!
