Spent some monies before tariffs started rolling in and got some phosphors (from the Netherlands).

Now I am making some new colors- a warm white and a pink. Mundy Hepburn was right- when buying phosphors- just get RGB... oh an maybe violet.

Gotta mix these on the ball mill for the recommended two days and then do some test coats- I sure am excited!

realistically I might do a test tomorrow. It will be nice to see how it moves and coats a sample tube.
It sure is coating the jar well after about 20 minutes. That is a 254nm quartz lamp for the argon mercury.

The nitrocellulose coatings are so effective! The chemicals are kinda nasty- but they evaporate rapidly and don't make phosphor waste that cannot be put down the drain.

I needed to mix a small bottle of nail polish to which I had added some acetone in order to thin the paint somewhat. This was a perfect job for my large paint shaker.

I needed thinner paint for some touch-up work at the exhaust port on the glider's turtle deck.

See next two comments to this post....

#ScribesAndMakers If you paint, do you have “recipes” or tricks for mixing colours, or do you eyeball it?

I made my own DIY paint. Crushed charcoal, eggshells, or flowers and egg white. The red in this was made of rose pedals and red cabbage, the background was just the back of an old box.

I thoroughly enjoy making funny, colourful goop. This is from an old series I called my "Paint Things"

My one trick is, not being afraid to get a little dirty.

I just finished my Grogu! It's a 3D printed figurine that was gifted to me for my birthday. I've most done it with the airbrush and a bit of brush work. Super happy with the results and it was very relaxing to work on a scale like that, not struggling to get the small details.
It was my first time painting a 3D printed figurine and I was really surprised by the quality, although I definitely need to learn how to clean it up properly.

The glider's horizontal stabilizer's paint needs scraping to remove runs and drips.

This part has a span of eight feet (2.44 meters). And I need to work on both sides.

Fortunately, the surface is convex, or flat in various locations...but it's happily not concave.

Setting up the work lights to give me specular reflections makes it easy to see and then work on the drips and runs.

I'm also learning that how I sharpen/sand the razor's edge (symmetric? asymmetric?), how I hold it (rake angle)...can make a big difference in how efficiently and effectively I can scrape away the high spots.
en.wikipedia.org/wiki/Rake_ang

The pile of shaved paint next to the razor was produced with one gentle pass...once I started figuring out sharpening geometry and rake angle. Before that, my progress was slow and required much more effort.

The glider winglets have been sanded and buffed/polished...well enough.

I did not use the polishing machine. These are small parts and somewhat fragile, so I buffed by hand.

The winglets have electrical connections (spring loaded car door jamb connectors, lol!) and a molded receptacle for these nav/position/strobe lights:

The 2nd and 3rd photos show a progression from ugly runs and drips...to a scraped surface that is almost ready for sanding.

The glider rudder has been wet sanded down to 1200 grit (first photo), rinsed and dried.

Using a coarse polishing pad and cutting/rubbing (not polishing) paste, and about 5 - 10 minutes of work with a dual-action polisher...I got decent results quicker than I expected.

This bodes well for all the work I need to do on the larger parts: horizontal stabilizer, fuselage, flaperons, and wings.
