Used on a electrially leaky distributor cap.
NIce stuff. I used this on a 5 cylinder, homemade, fiber distributor cap on a one-off handmade 5 cylinder radial outboard motor that hadn't run in over 30 years. It appeared there was some high voltage leakage from the center electrode to the 5 electrodes to the spark plugs so I sanded the carbon traces and coated the entire cap with this stuff. It worked.

Messy, tacky stuff that covers well
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.

Quality coating.
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.

Just what I needed.
I may save my faulty alternator yet and this helped greatly by protecting the wires on the rotor coil. Thank You!

Questo isolante รจ l'ideale per mettere al sicuro collegamenti elettrici, impossibili da isolare, una volta asciugato crea come un tappo solido, usato per isolare i contatti di una vecchia bobina di una vespa, consigliato.

Does what it says on the box

L'ho utilizzato per isolare le alette di fissaggio metalliche di alcune mie testine del giradischi che altrimenti produrrebbero un rumore di fondo una volta a contatto con lo shell. Passata questa vernice trasparente il rumore scompare come se ci avessi messo del nastro isolante, molto valida.
