I'm buliding a Telecaster and almost have all the pieces and parts.
And then it dawned on me, I didn't get any insulation.
I know alot of guitars (I have) that don't have or need insulation. But some have one of the three mentioned.

So, here is the premise; I have a high output Seymour in the bridge that has been custom wound, and a bridge also custom wound hot. I am using cloth vintage style wire. The question is ....Do I use an insulation?
If so Copper, Aluminum, or the insulation paint?-N 8)

The plain truth is, the majority of noise which enters into a guitar's circuit is introduced directly through the pickups. Consequently, if the pickups are shielded themselves, any extraneous shielding of the body is superfluous. Inversely, if the pickups aren't shielded, the same holds true as any extraneous shielding of the body remains superfluous.

You are right Martian,

But noise comme also by the pickgard and go by the wires. And noise could go trougt the body.

If you use high gain amp or preamp effects with high gain ,you could have some noise.

But if you don't use high gain, leave it original, This, won't give you any problems. Or just put black paint on cavities on the body. We see that on most guitars

I do 3 times insulation;two with black paint and one with copper foil ( Stewarts Mcdonalds).

I put copper foil on the pickgard.

I Each time, I could test the guitar before and after . The result was very good after: no noise

On time the customers ask me to insulate the pickups ( DiMarrzio humbuckers, open coil).

This make also a big difference.

Using these measures, you also ramp up the capacitance of the circuit, introduce eddy currents and suppress the full output and frequency response of the pickups. Turning the volume and tone down on an unshielded guitar will mimic the exact same effect.

Martian,

Like I write:" the result was very good after"

I mean that I never heard a difference in tone or frequency response after the mods. Same for my custommers.

Let us agree to disagree.

Thanks for the information. It is always appreciated!

I will put together another post (with pics) as I start piecing her together.

Do you do this kind of job and see by yourself ?

Acknowledged. Again, let us agree to disagree.

If I'm interpreting your question correctly, I've been doing this kind of work as tasked for over forty years. Under the headings of, "The customer is always right", and, "If I don't do it, someone else will", I perform these tasks routinely, regardless of my personal opinions which under those circumstances, I do not offer unless directly asked. Even so, I certainly will not refuse to perform the task. Granted, many cannot hear any difference and surely if the guitar was already OEM paint shielded, the difference would be negligible upon further redundant shielding but nonetheless, these attenuation issues are definitely there. So, the answer to your question is yes.
