I have a K6100 monitor that works fine (now) but has a lot of rust on it and the shield behind the tube. Rust even got on the frame-mount transistors (since replaced with new insulators) and the HV adjustment pot disintegrated.

I'd like to take the frame and shield and sand all the rust off and paint it with an aluminum-color spray paint made for painting metal. Will I have to worry about grounds? There are five wires from the neckboard and tube have eyelets that are screwed to the frame, as is the HV cage. Will my grounds be okay?

And what about the shield? Will paint affect it?
 
I have a 20ez with a rusting frame that I want to paint as well. My thoughts are that it would be fine. Since the grounds are screwed in, that should make good enough contact. What are you going to do? It will be a bit before I try this, since you know I have these K9200's to fix and a million other projects (thanks again for the help).

Chris paints them all the time.
 
You can paint it Steve, just make sure you scrape the paint away at the ground contact points. There are going to be some that argue the whole heat dissipation factor however, i've done a fair amount of temp monitoring before and after paint jobs and there really is no issue. In fact the monitor runs 4-6 degrees hotter with years of caked on dust an nicotine and a good clean monitor with a repainted frame runs 1 1/2-2 degrees warmer.

I don't have to paint them pink like he does, do I?

Thanks. I'll probably sand it good, then put some small round stickers on the ground points before painting. That way I can peel them off afterwards and have a nice connection there.
