Wrapping noisy single coil pup with cloth then copper tape to quieten?

I made a thread on another forum about shielding inner cavities with copper tape, but got band from a different section of the forums for no good reason really, so I can’t follow up on that thread.
I have a strat that’s unusuably noisy on distortion patches when simply connected to a BOSS gt-8 multi fx box with a Monster Cable and then headphones out of the fx box. Someone suggested in a thread that I remove the foil tape I added from all the cavities, as it does nothing but create an antenna for more noise.They said the best I could do was have flashing on the back of the pick guard where the tone pots are and ground one of the tone pots, both of those were already done when I bought the guitar.
They then said to reduce noise but will also loose tone is to remove the plastic case for the pick ups, wrap the exposed copper spooled wire with cloth tape, then wrap that with copper and make sure the copper comes in contact with the negative terminal of the pick up.
I’m hoping anyone here knows exactly how to do this. I have copper flashing for like house construction. One side is plastic coated. I can maybe remove the plastic then remove the glue with solvent if both sides need to be exposed copper. What if the copper comes in contact with the positive terminal of the pick up too? What if the cloth tape has glue on it or not? Etc.
Thanks. It’s a $75 new strat, but if I get it playable, I’ll be happy. Might switch out the pick ups to humbuckers or give it to charity/sell it cheap and get a much less noisy guitar if all else fails

Actually, the simplest way to quiet a strat is to get the "dummy coil" backplates from Lindy Fralin: Welcome to Lindy Fralin Pickups: About the Backplate Noise Canceling System - The Finest Guitar Pickups Available Today!

You can paraffin dip, but don't melt using flame burners, almost burnt my parent's house down when I was still living at home...

Or upgrade to Kinman (vintage) or Barden (very sensitive and clear), both highly recommended, and both completely noiseless.

Paraffin dip is more for stabilizing inside components (magnets, bobbins, etc...) so that they don't create noise by physically vibrating.

I've lined many Tele and Strat cavities with copper shielding. It helps some, in certain situations; usually better than not being shielded, I've noticed. I've never heard of wrapping the pup, and I can't imagine that would be better. And if you're going to lose tone to boot after all that work, it sounds like a loser.

What you need to do is create a completely enclosed conductive metal case for pots, wiring, switches, everything, and ground it; that'll be as quiet as it's going to get. Some people even run a bead of solder along the seams to be sure of no gaps. Replacing pots, wiring and jack with top quality also helps. Stew Mac sells conductive copper tape that makes the job easy, 180" x 2" about 20 bucks.

That Fralin thing looks cool. I think I need to try that!

My Recordings/Credits

100% screening will eliminate all of the buzz noises. All of my Fenders are done that way and if you take your hands off the strings, no buzz.

All the cavities are lined with adhesive backed 3M copper foil tape. Each piece is soldered to the next and continuity is checked with an ohm meter. The pickguard is also lined with copper tape.

On the strat pickups I carefully line the inside of the covers with copper foil. One piece is lining the bottom, the other wraps around the inside and those pieces are carefully soldered to gether. A small overhang is left to connect a ground wire to it. I use an exacto knife to cut the copper out of the pole piece holes. It's important to not let the copper touch the magnets. The rear of the pickup cavity is also lined with copper foil.

Hum is removed by the use of an active preamp circuit. I use a jap dummy strat coil screened and shock mounted internally. The circuit cancels hum via phase cancellation. There are two trimpots, one for gain, the other is a hum null. That design allows up to an 80 db s/n ratio, pretty good. My Fenders are as quiet as a well shielded Les Paul, all while using old 1960's era pickups.

All the pickups are wax dipped. They are shock mounted with no springs but latex rubber hose. Springs will feedback at high SPL's. All of the metal parts are secured and or glued with silicon glue to absorb vibrations, anything that's steel and can move will feedback. Yes, I play on '11'.
