Chuck, usually a thinned seal coat is used to even the surface and seal the pores of the project. If you use full strength, you can have spots that suck it in and other spots that won't hardly take it..you can see the effects when the light hits it..high and low spots in the finish. Doesn't make a tinkers dam on a deke. I do it on dekes for adhesion of subsequent coats..the thinned coat penetrates and the top coats stick to the seal coat...at least I think so and it makes me feel better.The "solids" are the material you are paying for..the rest of the can is solvent and flashes off or evaporates.
I was thinking on the later, that the thinned coat penitrates and would allow the following coats of paint to better stick. I think with Willy's cork sealer the extra solids might be allowing you to fill the large voids in the cork some, but I really don't know the thinking on the cork sealer with more solids. Not sure beyond that as far as decoys go.
