How is this compared to the permatex version
https://www.amazon.com/Permatex-8...742&sr=8-2

There is a $1.54 coupon on the permatex version and the permatex version qualifies for extra s/s discount ($2.41 after 5+ s/s products)

This is one of those I didn't know I needed it items but it can in darn handy when you need it. @$2.51 who in their right mind would say no because you never know and when you need this and it's sometimes in a big hurry. Cheap insurance. Thanks OP!

Just buy it now, throw it on your workbench and forget about it until you need it. Much easier than driving to Walmart and paying $7 when you really need it.

Anyone knows if this will work with plastic like on a truck camper shell? The hard black plastic that covers the tailgate cracked.

Also isn't it cheaper getting a tube of caulk that's comparable at HD?

Anyone know if this is food safe?

The cat's filtered water dish has sprung a leak and now she just looks at it sadly and then meows at me, as if to say "Quit buying crap for yourself on Slick Deals and get me a new bowl, Wench, I need moving water in which to rinse these toe beans."

She washes her feet in her water bowl, if you are at all confused.

Would this product work well for sealing a small leak or two (probably around a nail, but I'm not sure yet) in an uninsulated metal sunroom roof?

It's a white roof, but I'm more concerned about stopping the leak.

edit: I see that white is also available for $3.xx.

Yeah.. as a casual DIY and handyman for my own house, I always struggle to keep this kind of thing useful in the future.. Have to throw away like 80-90% of the material from time to time just because it's being shelved for awhile and become hard... try lot of ways.. from using plastic wrap to using a nail/screw.. nothing really work... Frown just hate to waste stuff...

Use JB Weld Clear Weld epoxy. Food/pet safe once dry

A quick google search returned that you should buy Food Grade RTV.

Have had the permatex version of this (likely the same) last a very long time after opening. Was able to use multiple times successfully.
