MGH,
you're probably experiencing what I found when I recently tried weathering a spitfire with the Flory washes, and that is some degree of orange peel in your gloss coat. The simple solution : in those spots where you have the little bit of wash left, a damp (not wet) q tip and remove the excess. The proper solution : glossing with no orange peel (which I'm admittedly still working on, by no means an expert) what I've read / learned from automotive painting websites, etc. is high pressure high flow when airbrushing gloss, though we don't want it dripping, it does have to 'flow' and 'pool' on the surface to a degree. From what I understand, orange peel is little droplets of gloss lying on the surface and drying, i.e. there is not enough gloss on the surface for all those droplets to join and create an even coating. Personally, using Vallejo's gloss thru my airbrush, I just can't get it right. Using Krylon acrylic gloss from a rattle can, I get a lot better of a coating. My solution, I'll be using the Krylon rattle can. Now, the Flory wash can work a lot better, and though there may still be the stain left, it is fairly easy to remove using the damp q tip. (Myself, I dip the q tip in a little standing water, squeeze it out with my fingertips, then run it over my arm / face to make sure it is almost dry, I've found this gives me the results I want).
This is only what I've found in my experience, you guys may be a lot better at this than me or find different issues.
Hope it helps.
