Hmm never heard of that.

 

 

If you are referring to the module a lot of places are tryin to sell them. It is VERY controversial if they work for vehicles.

Ya i krown my truck since new. Amazing product, I even have a warranty on it. The local krown sprays all the city ambulances. I also have a electric module buy don't really trust it. Either way I have both lol so should never rust.

Howdy I have always used chain saw bar oil on my vehicals twice a year once in the spring when its dry out and again in the fall. Drill holes and install plastic plugs in the bottom of doors, sills, tail gate and then spray the entire frame. Its a bit messy for a week or so. I feel using under coating cracks and finally resalts letting water and road salts leak in causing rust. I never found that the oil to harm wiring harness.
