Mr. Stache - Baby Blender v2 - Paintjob

I'm relatively new to scratch building and R/C but so far I've been able to complete an FT Old Fogey, and partially complete an FT Bloody Wonder (waiting on servos). I really enjoy scratchbuilding. For my older brother's birthday, I bought dual-pack baby blender speed-build kits. We've been able to scratchbuild them together via Skype (he lives in FL, I live in AL). It's been a blast to get to use this hobby to keep connected with my brother.

Let me explain my paint scheme. My students in the high school choir I teach refer to me as "Mr. Stache" at times. My real name to them is Mr. Stence; however, since I have facial hair somehow they thought that it fit and I usually let it slide. Ha! Hence the hipster biplane.

So as you can see, I used a stencil and spray paint for both the lettering and the mustaches.

I downloaded and installed a new font from dafont.com which is a great source of free fonts. Once that was done, I typed the text I wanted into photoshop and printed it in the dimensions I needed. Once printed I taped the paper to the poster board and cut out the stencil with an X-Acto knife. It's basically the same process with the mustaches, but with a stock image instead of a font.

I believe the font I used was called "Last King Quest":

I cut out a mustache on either side of the poster board so that I could use the edge of the poster board to line up with the edge of both wings so that my racing stripes would be straight. I had a little trouble spacing the mustaches apart from each other, but I could've fixed that if I just did a little more measuring. Also, you can see that on a few of the mustaches I saturated the paper with just a tad too much paint causing wrinkles. I wasn't able to hold the stencil down all the way while spraying a few of the mustaches which caused fuzzy edges.

Here's the spray paint I used. Flat Black - 96 cents at Wal-mart. 

If you noticed the speckled look on my fuselage and around my lettering, you should know that it was unintentional. I was trying to gain a little more of a grayish glow on the lettering when my finger bumped the stream of paint. Paint splattered onto my plane and I was not happy. I thought it may look better being speckled everywhere so I repeated the process on the rest of my plane. I'm afraid I was wrong! lol. If given another chance to paint I will most likely not add speckle to my paint scheme.

I have a few questions:

1. In the recent FT Spitfire Review, the guys from flitetest mentioned a new method being developed to paint foam board that may also waterproof the foam, so my question may already be answered. Does anyone know of another method for painting/stenciling on foam board that is not as messy, just as cheap, and/or easier? 

2. Of the problems that I mentioned having, could you guys please give me a few tips on keeping them to a minimum?

3. Are there any other methods of custom decorating a plane that you know of besides tape or stick-on decals?

4. Does anyone have any suggestions for painting over the tape hinge that it used to install the turtle deck? Did you remove yours and use hot glue?

5. Last but not least, does any one have any suggestions on how to finish out this paintjob? I'd like to do something different to the bottoms of each wing and the vertical stabilizer.

Thanks in advance for your tips!
