I was cleaning out a bit of PVA from some soaking parts and thought about this:
Have you tried model clear coats (Acrylics, enamels and lacquers)? Things like Testor's or Tamiya, etc.?
I ask because they are formulated to work on plastics.
I am going to dig out some old PLA prints that are trash and do some testing. But, beware that I am not using the same PLA as you.
I am using a variety, some to test with (Beer waste PLA for instance because of the caramel color) and PLA/PHA hybrids, etc.
But, I will let you know what I find tomorrow after I wake up and make an appointment or two.

I take it you are trying to coat your prints without paint or primer....just raw plastic.
Have you tried a polyurethane? It may be non-reactive. It can come in spray and liquid brush-on.
Also, try an acrylic spray. Or, even try a brush-on gel medium like this. It is acrylic based and have used it a lot when doing acrylic paintings. And, acrylics are just a plastic, so......
Anything with an acetone type of chemical in it for binding (like Krylon) will react to plastics to some degree.
I am not sure what Crystal Kote is made of so, no idea there and I looked it up and all I could find was descriptions of purpose and not content.
