We have a good deal of information but what is it you want to know - is the
coating likely to have been adversely affected? Yes.

Should you consider stripping and re-coating the assemblies after
troubleshooting is done? Yes.

Kerosene is a really good stripping solvent for most polymer materials.

I was once asked how an acrylic coating would behave when exposed to skydrol
(a really aggressive aviation hydraulic fluid) being sprayed onto a circuit
in the cockpit of an aircraft. My response?

It doesn't matter - the pilot has already left!

I hope this helps
