A Quick Shrink.
I emailed the Firestik Antenna Company for some extra black shrink wrap because I wanted to make my Firestik antenna quick release stand out less since it was chrome (yet most of the antenna base was black and the antenna itself was black). A few days after my email Firestik sent me some extra shrink wrap for free. I trimmed a piece and “installed” it over the quick release using my heat gun and about 30 seconds.
