Is there a good spray or paint-on treatment that I can apply to small electronic connectors before connecting them, that will help them maintain a good connection over long spans of time?
I am building custom lighting systems (indoor & outdoor) that contain connectors to separate different parts of the electronics. I've had issues with connections becoming unreliable over time (dirty? oxidized? not sure… the pins look fine), causing lights to flicker, and even fail, due to the connection. I'd like to find a way, short of soldering, to make these connections more reliable.

The following article may help you with some of the fundamentals you are looking into: A Perspective on Connector Reliability. A connector will always introduce some type of resistance and it will possibly fail over time. But there is a grease you could try to use for your connectors. NO-OX-ID is the product that appeared to be effective for corrosion, copper deposit, rust, and general connector defects.
