This got the paint on fairly smoothly and with no, or next to no, threads forming.

But even considering that, I don’t think it’s worth the bother and I don’t quite see how other people get along with it. I doubt I will be using, let alone buying, any more Mr. Color lacquer paints — but I like their aqueous paints a lot, so I will be using those
