Repairing the back panel of a HP-15c

[Maximilian Hohmann]

Hello!

I wouldn't peel it off. It doesn't really look bad and can only get worse. Your intended method of straightening will probably not work, no matter how many bricks you stack on top of it. If anything, then you may have success by running it through a manual printing press of the kind used by artists to print etchings and wood carvings.
Just put some contact glue under the side that is beginning to come off. And for touching up the type label on the front side I can recommend a "Chrome marker - High Gloss Liquid Chromium" that you can find on places like Aliexpress.

Regards
