conductive paint?

Post by TurkeyVolumeGuessingMan » Fri Jun 16, 2017 1:49 am

Has anyone used a conductive paint for super narrow spaces for lighting? I am wondering if it would be easier to paint a trail of conductive paint through a tight space such as between two wings in order to light something.

Here is a model railroading-related essay on this topic:

If you've done this, I'm interested in learning more about your experience. Thanks.

I have used Busch(German MRR) on a fighter plane.

Mixed results. Only tried it once.

I'm not entirely sure how to connect a wire to the paint when necessary. Just glue the wire down and paint onto it?

I have tried several and while it is a nice concept it has too many negatives- mostly a fairly high resistance. Using either bell wire or copper foil will work much better IMO...

I have heard that using Magnet Wire and SMD would be a option where you might want to consider for you lighting process of these tight places. I have seen where using Aluminum Foil to light the areas of which you're speaking of to reflect the light to the desired area - Keep in mind, these options i have not practiced myself but am looking at on a 1/1000 scale of which I'm doing right now.

Back in my teens my dad had an old car with a faulty heated rear screen. Some of the wire on the screen had either corroded away or been scraped off.
He went to Maplin Electronics (UK) and purchased a bottle of conductive metallic paint and had a small stencil which come with it. Painted it on the inside of the rear window and it took the current from that circuit no problem.

I wonder if you can still buy this stuff.

I had a defroster grid repair kit but it had adhesive backed foil strips instead

How do you connect the leads of the led to the foil? Conductive glue? What kind is best? Or a drop of solder and pray that you don't burn through the foil?
This IS my sig.

I just went low tech and wrapped the foil around the LED leads then used some heat shrink tubing to insulate.

I have successfully used the Busch paint - initailly I bought it to repair a damage in my car's rear window heat grill, and it worked like a charm! I have later also used it for LED connections in one or two mecha models, and the stuff worked well, too.
