It comes with a bottle of fluid used to blend it all in and remove the excess. I think the reason it works how it does is both the paint characteristics (tacks up very fast) and the blending fluid which appears to act on their paint but didn't cause any defects in the existing paint.

But that's just my impression. This isn't my field. As a consumer, yeah, I am all done with the traditional methods.

There's also info out there about how to do an "area" like a peppered front fascia for example. No way that'd work in the typical touch-up paint arena.

Yer black can't be as bad as my Tundra. I get a paint defect if my neighbor farts too loud........
