Iosso Snap & Zipper Lubricant Tube – 1.5 oz Silicone-Based Lubricant for Boat Covers & Marine Gear – Non-Staining Water-Resistant Formula for Smooth Operation – Compact & Travel Friendly Made in USA

The cover on my truck bed was difficult to unsnap and snap, used this lube on all of the snaps and it made a day and night difference in the ease of snapping and unsnapping the cover. Before I used this lube the snaps were too tight to unsnap and seemed that I was going to tear out a snap. After using this lube the snaps are smooth as silk and operate better than when new. As for staining my cover is black so I didn’t see any need to worry about staining, I could see some staining if your cover was a lighter color as it is pretty easy to apply more of this product than needed. I dumped some lube into a plastic cup and applied the lube with a cheap acid brush to ensure even coating and cut down on waste/ mess.

I bought this for the stated purpose and it works great, but now I'm using it for lots of other jobs aboard that benefit from a "clean" lubricant. It is VERY slippery and seems to stay where it is put. A medium gel consistency, too thick to work into tight places unless they slide together (like zippers and snaps). Works great on drawer slides, cabinet catches, even wood-to-wood contact surfaces. Completely clear. I'm ordering more for reserve.

Great product, as advertised. I would have rated it 5 stars had the applicator come with a extended nipple, for easier application on a small area metal zipper. The flat nose tooth paste tube applicator is messy and clumsy for the small zippers. You lose a lot of product if you are not careful. Otherwise the product is great.

Best product to protect and lubricate your zippers, especially marine. This is the easiest non messy, controllable gel to apply and it doesn’t stain. Been using it for over 15 years and will continue to do so.

Used this for years on all zippers really works

I have used this product on my boat cover with snaps. It works great and last for a couple years at least. Unfortunately the package arrived empty, looks like it was never sealed. I guess I am going to get a refund. I could not understand the Amazon rep. She did not speak English that I could understand.

I bought this for my sliding glass windows which were not sliding without a real workout. I cleaned the tracks with soapy water and applied this stuff. Amazing difference. So easy to open and close now. I wish everything were this easy! Thank you Google and Amazon!

I Take my bimini cover off yearly and once I put this on the zipper, the next year the zippers were still free and working like they should. The boat is left uncovered on Puget Sound, so gets plenty of rain and salt on it. I put it on my snap fasteners too and don't have to struggle getting the canvas unbuttoned like before.
