Yeah I found that Walmart entry too, but it's not orderable for me from anywhere, Walmart, 3rd party, not available in any store within hundreds of miles. I'd say it's discontinued.I found it @Walmarthttps://www.walmart.com/ip/Shoreline-Marine-Liquid-Electrical-Tape/28429509
That might be an old link, but they say they have it. I probably bought it from Amazon, but you're correct, it's not there anymore. Walmart can be really funky to order online from because they use vendors and rarely check up on them. Unlike Amazon, if you go through a vendor and the deal sours, Walmart will tell you your beef is with the vendor. We're not talkin' a lot of money here, so I'd take the chance if you can order it through Walmart.
I was trying to get you to stay away from Star Brite(in the yellow can) and another brand I dislike called 'Brush-On' by Bluemagic. I haven't tried all of them out there, but at least four major brands. The Shoreline Marine product was a head taller than the rest.
If you went to an industrial site that catered to people manufacturing boats, I bet you'd find a good product maybe even more durable than the Shoreline product.

It's weird to me that the Shoreline stuff would be that much different, since it's made by Star Brite.
West Marine makes a liquid electrical tape. There's also MDR, and Seachoice
