Dark colored enclosures. Now what?

These dark colored enclosures look so good! I buy them and then can't figure out how to do any labeling or artwork. Because I have no idea what the hell Im doing.  I have clear decal stock, which is likely to be worthless on this current dark maroon box, I have decal stock with a white background, which I think will become somewhat transparent and let a lot of milky-looking maroon through, no?  I have some photo paper also.
I recently put some adhesive backed clear stock on top of a yellow enclosure with just black type. It sucks. The black looks grey, and my clear coating layers (what did I do wrong here?) looked and felt so horrible compared to the unsprayed bottom of the enclosure, that I had to clear coat that too.
Really an awful job. Hammond's pre-colored enclosures have just enough of a mottled finish that the adhesive backed clear stock had faint, milky looking bubbles that I could not squeegee away. But sanding the finish just took me so very far from the nice finish I had bought.
Maybe I should just do some hand painting. A shaky and small job, but at least both the colors and finish will look nice. Is there a paint that would adhere well to the Hammond finish without requiring layers of clear coat? I would think that hand painting will be a little bumpy, and fine sanding (I have carbonundrum and several 450 and 600 fine papers) would screw up the hand painting. Trying to sell a pedal or two. By the time I get to this point, I am "so over" the pedal I'm close to just using stickers or a sharpie.

neither box-baking oven nor etching are possibilities in my particular apartment situation.

Is there a trophy shop nearby? Many shops will do engraving on just about anything for a very reasonable price, and in my opinion engraving (especially laser engraving) on a powdercoated enclosure is pretty much the coolest finishing job you can get. 8)

I use white water slide paper in these situations

I've painted a white shadow on a black box and then used the usual waterslides, handlettered with a lining pen and gouache paint, stencils.

Jon- I was hoping you'd chime in. Are you clear coating on top of your hand painting?  What is your process with enclosures?

I'd like to know more about davent's technique too.

Laser engraving on powder coated aluminum? Do you have some pics?  I called a couple trophy places, they said they can't do it with a laser.  ?  I'll try others.

For the white 'shadow' all i did was take a printout of the labeling, trace around each word leaving a bit of space. Used the drawing to cut the hole in a piece of masking tape, stuck the masking tape to the enclosure where the decal was to go, sprayed the hole white  (then a bit  of green), clearcoated then the decal was applied over the white shadow. Early effort with an airbrush trying to do a fade to the white edges but didn't have the skills to make that happen.

The big Savage Croaker was just a stencil cut with an xacto knife from frisket film.

For hand lettering with whaterever paint or ink is around, my best results so far have been with a lining/ruling pen, (takes me lot's of practice to get acceptable results). Also mess with a diy popcan pen and other carriers but so far inconsistent results.

I've entertained the idea of purchasing a vinyl stencil cutting machine to make stencils to paint light colored lettering on dark colored enclosures.

There are a few models that are reasonably priced and cut fine detailed work.

I just designed a new fuzz circuit! It almost sounds a little different than the last fifty fuzz circuits I designed! ;)

Pretty much anything Pickdropper does is a perfect example. I can't remember who said they used a trophy shop. I use a regular CNC machine, not as clean looking as the lasers in my opinion.

As far as hand painting goes, I've heard that automotive pin-striping paint will adhere to just about anything.  Obviously it's made to be used on fully cured factory car finishes.  I've seen good results on poly-finished guitars.  Haven't tried it myself, but considering it.  What does Z. Vex use?

Paint markers work very well. The ink is opaque, really durable, and compatible with everything I've used it over (bare aluminum, enamel, and powdercoat).

The downside is that the tips are pretty wide. You can use an X-Acto blade to shave the tip down and make it skinnier but it's hard to get it ultra-fine. Even with a shaved tip, it is only as good as your hand is steady. The potential is there to do some really good work, but it would take someone more skillful than I am.

**edit: I should add, I've only used Sharpie brand "fine" tip markers. They aren't very fine at all but they were all I could find locally. In the Amazon search link there are some sharper pointed Sharpies and also some from other brands. Maybe those would work better.
