Spray paint (or any kind of paint over the entire bezel or strap) brings its own problems, since unless a special additive is added to the paint to keep it flexible, the paint will become brittle when it dries while the resin bezel and/or strap remain flexible. When the resin flexes -- like if the bezel gets bumped into a door frame -- the brittle paint can flake right off.
And of course, the surface of the bezel looks different because of the painted surface, and an extra layer of paint in the "button holes" can make the buttons squeak when pressed. That's probably a big part of why "dyed bezel mods" around here outnumber the "fully painted bezel mods" about fifty to one. ;-)
And since Canadian007 only needs to touch up some slightly shiny spots, not change the entire color, there are easier ways to do that....
The bezel has some minor wear, nothing too bad. There are some parts where the bezel is slightly shiny. From what I saw on youtube, people used the enamel paint. I should try to colour the lettering. This feedback helped a lot, hopefully my first mod turns out a success.
As mentioned above, "slightly shiny" is easy to fix:

If you've used any of the previously mentioned paints before, it's probably best to stick with what you know and forget about what some guy(s) used on YouTube.

I have used dozens of tiny bottles of Testors oil-based enamel on lots of different projects over the years, so I already knew about how fast it was going to dry on a bezel and how much thinner I needed on a paper towel to wipe off the excess without removing ALL the new paint. The ONE time I need to try using a water-based acrylic paint on a bezel, I was surprised how quickly it dried and how hard it was to remove the excess paint, so I'm staying with enamel from now on. ;-)
