37-116 tube shields - Ronin61 - 09-29-2013

I want to paint my tube shields and need sugesttions on what paint to use and what color. Also do I need to remove the plating and how do I do it?[Image: http://i1281.photobucket.com/albums/a508/ronin61/th_null_zps9f450207.jpg]

I do not know what paint if any has been used on tube shields (have not seen painted shields, only plated) but if you do, make sure the inside surface that provides the contact with the chassis is not painted otherwise your shield won't be a shiled at all, and of course the paint should take the temperature rise without smoking or exuding some noxious fumes.

Aluminum foil might do as a temporary measure until you can locate proper replacements.

I've had real good success using Simichrome polish and a stiff cloth buffing wheel to clean up tube shields. If really bad, scrub them with Barkeeper's Friend sink cleanser and a Scrunge pad, them polish them with the Simichrome. You'll be amazed what they can turn into. Take care, Gary.

If the problem is just rust, put some naval jelly on them and let them sit for about an hour. Then rinse them off and the rust will be gone. You can get naval jelly at any hardware store. I use it all the time to get rid of rust.

They were originally tin plated.

I found that Krylon Satin Nickel spray paint seems to be conductive; at least, when I have painted chassis with Satin Nickel, the shields were just as effective...and I have measured resistance from one point of a chassis to another and obtained zero ohms with Satin Nickel sprayed on the chassis...

Thanks everyone I think with all the responses I got what I needed.
