[Amps] FW: RFI Question

[Larry Carman]

Didn't see anything at Allied or Mouser but ran across the site below that
sales paint and paint additives that are supposed to have RF shielding
properties.  Be nice to know they are effective or not.

There WAS a spray-on RFI shielding "paint" available many, many moons ago,
per a "New Products" listing in QST, back in the early/mid 80's, as I
recall...

The writer touted the advantages such a product offered when trying to
"quiet down" the likes of computer keyboards, et al (the Commodore 64, &
others of its ilk, was just beginning to make inroads into the shack, &
causing RFI to HF receivers)...

I'm sure something like this must still be available --- have you checked
Allied, or Mousser...?
