Conductive paint on homemade sugru? Answered

I've seen both instructables seperately, but would the paint work if applied on the homemade sugru? I believe I could make a speaker more soundtight with the sugru, and the paint would make the conductivity better.

Speakers are sophisticated electric motors.

If you can improve it with surgu, I will bow to you !

it's not an improvement of the actual speaker as much as the casing, the sugru will better seal the box and if the wiring is direct contact with the right parts of the speakers, it will be more reliable than just a thin wire that can easily pull loose

Sugru is a good sealing and holding material... but it cannot outlast the millions of flexes experienced by the voice coil braid wires which outlast the speaker cone MTBF.

While this won't work out, you should keep using your growing understanding of materials to come up with novel ideas.

on the outside of the speaker, the speaker is already made and I'm not changing it any. I'm putting it in a box and so I need to seal around I

You don't need to put a seal between the speaker and the speaker box. If you want to seal around the speaker wire going into the back of the box you can use basic calking or hot glue.

If your speaker has a bare wire that can come loose then you need to insulate that wire and solder it in place.

I'm having to cut holes to put the speaker in the box and they won't be exact, so I need a way to seal the gaps

Surgu is a rather expensive option to fill gaps. Some cheap bondo will do the trick if the cut is that bad. Or even some dry wall mastic will work. If the back of the speaker isn't vary flat and you are worried about gaps there then some cheap foam weather stripping will do the trick. Still don't understand how conductive paint fits into all of this.

What homemade surgu are you talking about? If your talking about the earaser putty then no it won't work well together.

What kind of speaker are you trying to make? Where are you planning to apply the fake surgu? I fail to see how conductive paint on that stuff would be helpful in a speaker application. Are you having the coil wires attach to the cone before going to the speaker terminals? The fake surgu won't do well to attach the wires and will add too much weight to the cone. Adding a conductive paint to the outside will have no affect on the overall build either.
