MG Chemicals4226A Clear Insulating Varnish, 55 ml Liquid Bottle

Works well. It smells very strong tho, but I guess It is supposed to be like that :)

This stuff is pretty tacky to the touch, and let me tell you it is extremely difficult to clean off of anything it comes in contact with (from clothing to hands to your work surface) so be sure to wear gloves and protect things well when using it.Does not smell as bad as people claim in the reviews. Kind of like a mild nail polish.Coverage is pretty good. It could be thinned (as they even recommend) to be sure that it gets down into the windings better, but for the purposes of a simple restoration it works fine. The brushes they give you to apply it are pretty garbage though - pick up some better brushes made for oil-based paint.One thing I wish it had was instructions or directions along with it. They provide a small pamphlet with danger warnings, and the bottle itself again has warnings, but there are no instructions anywhere to be found. I had to return to this listing just to find the recommended cure time and information about application. They recommend going to the manufacturer's website for this info as well, but this should absolutely be included with the product itself.

It worked great for varnishing the new coil in an induction heater after rewinding. It dries on its own but I put it in the oven anyway. Excellent product, I will buy again.

I don’t have any experience with the original ‘4228’ product, but this lower HAPs/VOC formula seems good. After about a week of cure time, a heavy coat dries to a glass hard, durable finish. Smells like nail polish. Of course, as with any solvent based lacquer, coating, etc., do it outside or in a well ventilated area.

Wish brush was mounted in lid. Lid has a pesky child safe feature you gotta really push to open...I jb them back to normal. Coating is more for coils than PCB. Might make PCB a little too hot.

Used it on a 1906 motor. Seems ok. Hardens up nice. Looks nice. Who knows.

Works exactly as I needed it to!
