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.

Cleaned and coated my copper piping system for my air compressor. The copper remains shiny and clean just as if it was freshly shined with steel wool. If using steel wool be sure to removed 100% of fibers to prevent rust or corrosion issues. My project came out great and cools hot compressor air to extract moisture in tandem with a water separator. If you like precious metals to remain pretty give this a try.

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.

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.

So far it works well and was easy enough to apply. Other reviews do mention the spray nozzle being defective so I am keeping an eye on that.
