It actually got me to give my airbrush (a paasache VL) a closer inspection and sadly I found that 2 of my three needles have damaged tips (no wonder they've been driving me crazy) and I was able to adjust the needle bearing to fix a problem I've had with paint getting into the trigger area.
Though a lot of that was because after watching that video I had to do a search on Ken Schlotfeldt and found this site:
https://sites.google.com/site/donsairbrushtips/home
Some of his tips contradict Ken's tips but they both have tons of great info.
And after reading Don's site (I'm still working through his airbrush reviews but have read the rest in it's entirety) I had to try spraying some food coloring tonight to practice and see how fine of lines I could get. Out of curiosity I grabbed some scrap foamboard (my daughter had finger painted the other side causing it to warp) and put some expired food coloring in my airbrush to try. Wow. That worked way better than I expected! In fact, even spraying it on really heavy I wasn't able to get the board to warp. This could be because the board was already warped from the abuse on the other side...I'll do some more tests on virgin board this weekend. But I'm cautiously optimistic about the possibility of using food coloring for painting foam board. It sprays great in an airbrush, gives nice vibrant colors, is super easy to clean up ... of course the downside is it will probably run like heck if it gets wet. But I'm thinking I may try minwaxing over it....
Time for some experiments
Thanks again for sharing this!
