Rubberized Plastic

 

the CF-readers that work on my Mac

If you bought any soft-touch rubberized plastic stuff, you may know that it becomes a sticky mess over time. Somehow they made plastic worse. This coating is difficult to remove, even with nasty chems. Some of these devices were expensive and/or not being made anymore. I'm sure manufactures don't mind all this tech going into landfill. 

I've primed & painted several sticky items now, and this does seem to work. For example, see this decade old CF-Card-Reader. The plastic case comes apart, and I test-sprayed it about a year ago. While there is a possibility the paint may soften someday, it has remained non-sticky thus far. I suspect water-based acrylics might not work as well.

Some cases are difficult to open and can be very sharp; I cut myself extracting a hard-drive. Another idea is to 3D-print a new case, if you're willing to sink more time into it. 

Learned my lesson - avoid rubberized plastic.
