Have you given thought to mixing white with say.....a clear? 1.) You're not going to get any spitting or gritty appearance and 2.) with enough layers I feel like you'll get the results you're looking for. It's a more gradual painting process and you get to dodge that spitting and all that's associated with white paints. Just a thought.

I'll give it a try!

You are an extraordinary painter facing one of the great challenges of weathering. You have both my admiration and support. The color depth and overspray are very realistic!
I guess I want to helpfully add you might try using masking tape to remove the paint as well. You can vary the stickiness by applying the tape to a clean cotton shirt beforehand; each time you stick the tape down it becomes less tacky. For what you are doing you might want to try a light pressure with blue tape, for larger uneven wear.

Thanks for checking in Bruce.
Tape only works if the the top layer of paint is on an unstable foundation. Which is something that most modelers try to avoid. However, the chipping fluid purposefully adds instability to that top layer. Dissolving that fluid layer with water dislodges the top paint layer into fragments and the result is (hopefully) realistic paint chipping. In my case, the chipping fluid beaded up on the base surface and created little dots of unstable white paint. Which can be lifted off by adhesive tape but it doesn't look good. The dried chipping fluid is also elastic and will pull off paint in bigger than desirable chunks. So I'm going over the model with micromesh, trying to create small areas of wear and encountering pockets of the chipping fluid, which is pulling the paint off in big chunks. These areas are being addressed by tape pulling/micromesh to remove as much of the unstable chipping fluid layer as possible even down to the plastic in certain areas. These areas will be repaired with RLM 74/75/white. It's a not a great situation but I dug my own grave on this one.

I'm sorry to hear your troubles with the chipping fluid. Forgive me if you mentioned it already but did you put down a gloss coat before the chipping fluid? I could see that causing it to bead up but not on a flat surface.

I didn't put a gloss coat over the RLM 74/75 but the AK Real Colors are semi-gloss. Typically, chipping fluid is applied over metallic paints which tend to be on the smoother side too so I didn't really think the 74/75 would present a problem. The areas where I burnished the cross markings down with Micromesh exhibited the most beading so I think the smooth finish and not anything chemical was responsible.
Here is an example of some of issues I'm dealing with. If the effects were on a smaller scale, I'd be able to utilize them but the areas of white paint that were lifting were too big.
These areas were resprayed with RLM 75 and the white overspray was re-established over that.
Concurrent with the repairs, I've been trying to push ahead and have painted the the yellow areas under the nose and the yellow ID band around the rear fuselage.
No masking problems for the yellow areas but the black chevrons revealed some new repair areas.

I really hate it when a build tries to kick my a$$ ESPECIALLY in the painting phase. For modelers like us that put ALOT of prep work into our paint whether it be aircraft or auto modeling alot of modeling hinges on the proper paint / finish outcomes and this can be
extremely frustrating when things go wrong. Keep hangin' with 'er John. I'm looking forward to the recovery efforts and successes.

It's frustrating but self-inflicted. I knew I was headed for trouble when the chipping fluid started beading up. I should've wiped it off right then and there but decided to press on. I've encountered this before so I'm not too worried about it. It's just a pain in the butt to see perfectly masked markings get flaked off bit by bit.

That's exactly my point. It'll bring a grown man to tears.
