...and not too bad on the bezel -- SO FAR!
Sometimes I want the "traditional" look of a metal bezel on my G-Shocks (or even an actual metal bezel, if anybody made one that wasn't deliberately "bling-y.")
I've tried dying a couple of them different shades of gray, and have followed a couple of threads where people talked about painting them -- but "normal" paints become brittle when they dry out and there's no telling how well they're going to stick to a flexible plastic G-Shock bezel when they're worn. I knew that a couple of paint companies add "plasticizers" to the paint to keep it flexible when used on automotive parts like bumper fascias and deck panels but hadn't worked with it myself.
Recently I found out that Rust-o-leum and Duplicolor now make flexible spray paints specifically FOR plastics, vinyls and other flexible materials! The first one I found in a store was Duplicolor's Flexible Bumper Coating in "Medium Silver" and despite the NAPA paint counter guy knowing absolutely nothing about it, I decided to give it a try on some old bezel-dyeing experiments that I didn't like.
After shaking the can VERY well, I was pleasantly surprised to see that this "coating" comes out of the can in a VERY fine, rather translucent mist. (All of my recent "rattle can" projects have involved automotive primer and dark flat enamel, so this stuff was quite a switch! Since the can calls it a "coating" I was half-expecting the material to be much thicker.)
I put many very light layers on the first bezel -- it probably took six coats until the "coating" was completely opaque and then I gave it a few more. I sort of hurried on the second bezel because it was getting dark, so I sprayed it on a little thicker in about three coats. Because it comes out as such a fine mist, it dries very quickly -- and it also didn't fill in small details like the recessed "mode," "adjust" and "start-stop" lettering.
After they had dried for about 24 hours, I tried filling the "G-Shock" logo with black acrylic paint, but the excess dried a lot more quickly than I'm used to when doing lettering with Testors enamel. That made the "wiping up the excess part" a lot more difficult, so I didn't even try with the smaller lettering.
Overall, I think they came out looking pretty good -- I'm not sure why they came out as slightly different colors. The one on the left looks more "silver" while the one on the right has more of a "bronze" cast. It might be due to the dye colors underneath, but I suspect it had something to do with "many light coats versus a couple of thick coats."
Now the BIG question becomes "how well will that paint/coating hold up to normal wear and tear of a G-Shock?" I have no idea but I'm hoping to find out -- I gave one bezel to a buddy who admits that he's hard on his watches. As mentioned, the stuff is designed for car bumpers, designed to be flexible, probably designed to be somewhat weather-resistant, and Duplicolor claims that it " ...offers a uniform, solid color with superior adhesion to thermoplastic rubber and polyurethane bumpers that won't flake, chip, or peel."
My expectations are very much in the middle of the road: I hope that this fancy coating holds onto the bezels better than traditional spray paint would, but on the other hand, I'm not expecting miracles! I'm planning to update this thread with new pictures when they start to show signs of wear, but a little part of me is HOPING that they'll still look like this next year...and the year after!
