Well I decided that it's time to take the plunge and repaint my gun handle on my beloved ST:TNG. I looked around and didn't see much info but had a few helpful hints passed along. This seemed a good excuse to document my successes and failures of my rattle can approach.
Step 1: Disassemble gun handle from machine. This came right off no problems here. Once handle was off, it was a simple matter of using a security bit to remove the four screws holding the two sides of the handle together (plus 2 regular screws).
Step 2: Assemble the supplies. I headed down to Lowes and selected a spray on stipper that seemed easy to apply. I am spraying into a metal paint tray on top of a thick drop cloth. I bought chemical resistant gloves and some scrub pads. I picked out high gloss paint and a spray on clear coat. Total cost of supplies is under $30 USD.
