Dolphs EB-41 is the product I use. Pretty sure Spray-on doesn’t do black

This is the stuff that I use on my old stators/coils. I find that this stuff works very nicely. It appears to have a consistency ligher than water and really soaks into the coils rather quickly. So far I've sprayed four coils that buzzed like an angry hornet's nest with a 100% success rate at curing the problem. Make sure you buy the clear one, that works the best.

That SprayOn brand varnish is what I use as well. You can soak parts with it until it's dripping and still dropped amazingly fast.

Another SprayOn clear EL600 electrical varnish addict here!Every single fan I own and have done for others has been treated with EL600 in the motor windings and choke if applicable.

Another vote for Spray on. After it dries you can tape off and use flat or matte black spray pant in light coats  to do the job. Just make sure that the varnish has had enough time to dry before painting.

I use the clear Sprayon because it is thin and soaks deeply into the coil. Dolph’s black is kinda thick and plasticy and lays on top of the outside of the coil. It probably traps heat inside. The only time I use it is to cover up a coil that has been previously sprayed hideous red or green.

I also use Sprayon clear. I agree with David, looking through the motor vent holes and seeing a red or green stator is a very hideous sight.
