The sole function of the shield is EMI (el. mag. interference) rejection/containment.
If anything, it will keep the tube hotter as it impedes the natural air circulation.
If your shields are clean, leave them alone.
If rusty, apply anti-rust agent, clean, rinse, dry and then leave them alone.
If used to be chrome plated (this is strictly aesthetic) - clean, plate, leave alone.
Do not paint.
And, one more thing, when you go to some questionable website and read some questionable articles, do yourself a favor, at least ask for opinions other people with experience, like the folks here - many of the got tons of experience and will gladly help.
This will save you time.
Time is money.
Money is more radios in your collection.
And remember, you are a radio restorer, not a painter.
