Thanks for all the responses. Gary, you actually answered the other question I had rattling around in my head. I was wondering what I could use to thin Floquil. I was starting to run some of the Old Silver through my airbrush and it just seemed to spit out. It wasn't bad but it wasn't as smooth as other times when I used Floquil. I was hoping that thinning it a tad would solve the problem but I think I determined that my airbrush just needed a good cleaning.
I ended up using MM metalics on my F-89 and for some strange reason, it's actually holding up perfectly in spite of all the panel masking I'm doing with it. Granted, I'm "de-sticky-fying" it by using my fingers but not a single microdot of the MM metalic paint has lifted off.
I've said it before and I'll say it again. 99.999% of my builds involve pure luck more so than skill.
