Krylon Fusion for Plastic paint as a brush-on?

Is there a brush-on version of Krylon Fusion for plastic or similar product? I often find myself touching up long thin scratches rather than wider areas, so the spray paint version isn’t as practical. There are some traces of such a paint on the internet but it appears to have been discontinued.

I recently did a royalax canoe in it and I could only find it in spray on cans

Spray some in a plastic cup . Now go paint your long thin scratches.

yeah, that’s the obvious solution I’ve been doing. It’s not the same though, since it dries up pretty quickly in that cup, unless you spray so much that it becomes wasteful.
