Not trying to fight Jerry, just can't understand the LGB oil over a product apparently designed for (at least pretty closely) the purpose you want. In my experience a thin film of oil will pick up more dirt and grit than one of these type spray coatings.

Hi Greg,
At this time I am not looking for the best long term solution but rather a short term test for practicality.
3M 5 Way and CRC 2-26 are very similar products designed for virtually identical applications.

3M 5-Way Penetrant[/b]
Displaces moisture and dries out electrical apparatus. Helps prevent shorting and increases conductivity. Inhibits rust. Frees rusted bolts, lubricates and cleanes, drives out moisture. Also excellent as a tapping liquid for stainless steel and aluminum.

CRC 2-26[/b] displaces and seals out moisture. Prevents corrosion, cleans, lubricates, penetrates. CRC 2.26 is a stable, inert organic formula , especially prepared to prevent and repair electrical failures due to moisture, corrosion, dirt or friction. Contains no silicones. Non-flammable.A '6 in 1' product:
1. A moisture eliminator - for wet equipment.
2. A moisture barrier to prevent trouble before it starts. The protective film seals out moisture.
3. A lubricant - lubricates contacts.
4. A penetrant - frees rusted or corroded parts.
5. A protector against corrosion in all electrical equipment..
6. A cleaner - apply to a corroded area - the solvent system in 2.26 will act as a degreaser.
It is because both 3M 5 Way and CRC 2-26 are aerosol penetrants that I do not wish to start with them but rather to first test with LGB Oil which, instead of being a penetrating aerosol (going everywhere), comes with a needle point applicator that will enable me to place a tiny drop on the chuff wires which will transfer to the brass strips and should prove to my satisfaction if I wish to pursue this method of chuff control or to instead switch to mini-magnets to be attached between the brass strips.
If I start with an aerosol penetrant it will instantly coat the very surface where I would want to permanently attach the magnets and the film left by the penetrating oil will need to be completely removed for any hope of an adhesive to stick where the penetrating oil was sprayed.
The best method of removing the penetrating oil oil would probably be an aerosol contact cleaner such as 3M™ Novec™ Contact Cleaner Plus

This means that I could end up spraying (into the confined space of the K-4 gearbox) first an aerosol penetrating oil and then an aerosol oil solvent both of which could attack the lubricants Accucraft had used for the K-4 driver etc.
Its not that we disagree on what might be the best solution to one situation but rather that I have not yet determined if I want to go the lubricant or the magnetic route for increasing the reliability of the K-4 chuff sensing.
I should clarify that 3M chemical products were a secondary line for me. They were manufactured by a different 3M division and sold by their own sales force but parts of their product line were made for and marketed by my division (Electrical Products). My division's primary responsibility was for products designed for electrical wire and cable management (insulating, connecting, terminating and identification) up through 35,000 volts. By no means was I a specialist in lubricating products.
Regards,
Jerry
