303® Aerospace Protectant™ for Conditioning and Renewing both New and Older Zippers

303® Aerospace Protectant™ for Conditioning and Renewing both New and Older Zippers - Makes them glide easier.

I have these heavy, plasticky-looking zippers on some heavy coats, sleeping bag, my SUV and the enclosure on my boat. After a while, all of these are harder to work, especially on my SUV and boat. I notice they look a little chalky, too. What's going on?

Answer: 
These zippers are made from a durable hard plastic called Delrin. Delrin is a high quality material of almost metal-like hardness. But over time they do become hard to work, especially those exposed to UV light.

 303® Aerospace Protectant does penetrate and bond to Delrin. Close the zipper, spray 303® Aerospace Protectant into it and work it back and forth a couple of times. Then unzip and wipe dry with a dry, absorbent cloth. 303® acts as a wonderful dry lube for Delrin zippers. It will make your zippers work `like new'. Use 303® regularly and you'll never see any oxidation either.
