HP-67 Shiny Spot on Face Message #1 Posted by Colin Verrilli on 3 Aug 2012, 10:10 a.m. 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: https://picasaweb.google.com/lh/photo/C-RthKo3OFAsPESnjXWb3DJFQUrqvbY7ReWm5TggMMM?feat=directlink https://picasaweb.google.com/lh/photo/RtH8bbztg4XbOkKQf2DUHTJFQUrqvbY7ReWm5TggMMM?feat=directlink Has some outer finish worn off in this area? Is there any way to restore the matte finish to this area? Edited: 3 Aug 2012, 5:20 p.m. after one or more responses were posted

Tons of good material there. Someday, it might even become a book ;-)

Re: HP-67 Shiny Spot on Face Message #7 Posted by Colin Verrilli on 4 Aug 2012, 8:57 a.m., in response to message #5 by Randy 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.

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

Re: HP-67 Shiny Spot on Face Message #9 Posted by Colin Verrilli on 9 Aug 2012, 5:20 p.m., in response to message #7 by Colin Verrilli 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!
