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.
