Ok, again, it's blush.
No it's not. If you look at the pics, you can see a regular pattern to the "stripes". They are called "wipe-down" tracks from using too hot a solvent or using too much solvent which pooled and softened the paint before it evaporated.
It's as obvious as the nose on my face. You can see every stroke that the OP wiped down the body including where he tailed off as he got to the edge of the body.
Blushing occurs where the paint pools and is thickest. It typically follows the outside contours or "rim" of the body where the paint builds up before spilling over the edge. There is no way the OP sanded such regular ridges in the body to have low spots for the paint to accumulate in. It would have looked like a washboard.
While the instructions may have said "use wax and grease remover or rubbing alcohol" for paint prep, they don't tell you how to use it and too much allows the solvent to soften the paint before it evaporates. This is why I use mineral spirits. It degreases, leaves no haze and doesn't affect lacquers regardless of how you apply it. The only thing you have to watch is that it is fully dried before painting as it evaporates slowly.
