Iosso Snap & Zipper Lubricant Tube – 1.5 oz Non-Silicone 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.

Works 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.

Great stuff. This worked very well on boat cushion zippers that were unused for 5 years. If you use this, load in a hypodermic needle tube so you can control where it goes and how much you use.

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 have used this product for several years and made this purchase to replace a partial tube I gave to my son for his boat. I use it on zippers and boat cover snaps. It doesn't take much and seems to hold up for long periods of time. It is pricey but it does what it says it will do and a tube should last a long time.
