Nitro Finish Hazing

I've noticed that after about 10 coats of shooting SW nitro clear over sunburst Strat (dark, black edge) that the lacquer seems to look hazy or foggy in the areas between the horns next to the neck pocket. Not noticeable over the front and back lighter colors...just the dark and blackish edge and horn area.
Any one ever had this or know what it's from....2 to 1 mix, shoot wait 1 hr, repeat up to 5 coats, wait several days, sand repeat.

That could be blushing, moisture trapped in the finish. Sometimes you can wait it out and it goes away on it's own. You can also try a coat of just thinner or blush eraser which rewets the finish and allows the moisture to escape.
