Bummed out that your Gateron clear caps aren't as, well,
clear as abostudio caps? There's an inexpensive fix from the Plastic Modeling world. Oldpharts know it as 'Future'; a few years back it was rebranded as 'Pledge Floor Care with Future Shine'. What it
is, is a liquid acrylic; dipping clear plastic parts in it (or airbrushing, or even
handbrushing; the stuff self-levels) fills in tiny pits, scratches, and imperfections. The end result?
The left side is stock, the right side dipped once and let dry for 30 minutes. You could do two dips, giving at least four hours cure time (depending on temp and humidity) if you need to. I haven't noticed any catching or binding of the plunger; if you're concerned, a quick swipe around the plunger opening with a cotton or foam swab dipped in isopropyl alcohol will strip the coating. Best of all, it's cheap - it sells for $6/Qt in the US, which is more than enough for thousands of switch covers (or plastic models; I've used less than 10% of a bottle I bought in 2003), but if you know anyone who regularly builds plastic models, odds are they already have some you could
mooch off of them borrow.
