DIRECTED (Latex) SPATTERING Paint Chipping/Flaking Technique
This is a simple, yet potentially powerful addition/variation on the latex-spattering technique - intended to direct, or concentrate, paint-chipping in desired areas, as shown above - without losing the randomness inherent to the basic, spattering approach.
For (just one) example, paint chipping on aircraft is frequently concentrated around panel lines - where turbulence pulls on the edges most forcefully - and particularly around maintenance panels/doors, where scratching and chipping from rough handling (slippage of tools, etc.), gives the process a head start. I recently got a chance to try the method - "full-blown", as it were - on just such an example: my depiction of Geof Fisken's B-339 (export) Brewster Bufflao:

Starting from the basic technique - metal-finish undercoat, followed by latex-spattering - one then paints heavy layers or "mats" of latex into areas desired to be free of chipping (or with reduced chipping - see below). Here, to concentrate chipping along panel lines, I simply painted a latex mat into the central area of each panel, with somewhat irregular edges (easily done ).
The idea is that all spatters in contact with each mat can be removed by pulling up the latter - after permitting it to dry thoroughly, of course - but before painting on the top color(s). And it is particularly useful/required for area(s) too small to manually wipe off some (dried) spatters while leaving others in place. As for the latter, with this mat-removal technique you need to verify closelly that you've laid on enough - however if not, then after painting on the mats you can still go back and do a little more spattering, over that general area. This, of course, has a limit: excessive spattering, and/or too-large spatters/drops (relative to the panel size) - in other words, having contiguous contact/overlap between spatters - will result in the mat(s) removing everything catastrophically (if fascinatingly ) in one, long chain.
Assuming the above is done correctly, then after pulling up the mats (and wiping stray spatters from remote areas), top colors are sprayed and the method completed as per the basic technique.
The above confines chipping to the area(s) outside each mat, leaving the remaining area(s) completely chip-free. If (relatively) sparse, overall or "background" chipping is also desired, then, after mat-removal (but before final painting) everything can be spattered yet again. Note these steps could even be repeated multiple times - painting progressively smaller mats into the center(s) of each "low-spatter" area - to produce a truly graded pattern of chipping. I have not yet tried this, but - again, given care not to exceed the maximum workable spattering density - I have not doubt it could work just as well.
How well? Here, you be the judge:

To correct the above, touchup-painting over selected chips made for an easy correction, on the finished B-339 Buffalo build. But the droplet sizes in the original spattering could probably have been varied more - or certainly, the mats could have been painted with small "arms" extending through the panel edges, to explicitly break the patterns, at selected points.
Either way, the technique has clearly proven its potential to create these - and no doubt even more - effects.
Pretty cool, eh?
