I hear ya John.
I have some micromesh and its great for smoothing out some rough paint spots without taking off the paint. If I do any weathering now before a gloss coat it will be to put a filter down on the paint to alter the tone or hue. I know some guys do this after a gloss coat but for me I find the gloss coat doesn't allow the filter to penetrate the paint to alter it. My filters are usually an enamel medium over acrylic. Some guys spray it on but i prefer to us a broad brush as I like to insure the brush has very little of the filter on it when I brush it on. The technique as you know is much different than a wash.
Cheers,
Dave
