ProtectaClear 6 Oz. Clear Aerosol Can, Protective Coating for Metal (Net Weight)

Works really well on copper sinks. However, it stinks really bad until it dries.

A great product! Absolutely clear and undetectable on my copper jewelry.

This did not last long at all! I feel I wasted over half the can learning how to use it properly. You need to do quick sprays and don't go over the same spot twice. Runs out quickly and a lot of waste, but it's the only thing to use on chains. Love the product though.

Works great but soooooo expensive. I think there’s another product that works just as good for metal jewelry that’s a fraction of price

I sprayed it on new chrome shower fixtures - handle, backplate and shower head. Tested it first on another part I wasn't going to use. Found it best to spray on vertical surfaces (so that excess product wouldn't pool) using light coats that overlap from about 12 inches away. Product leveled nicely and was invisible when dry. Just one negative - I used masking tape to protect pipe threads. When I removed the tape after drying a little of the sprayed on coating came off with it. I should have run a knife around the pipe to separate the coating on the tape from the rest. Waiting to see how long it lasts against our salty water.
