Great Stuff 99112876 Smart Dispenser Multipurpose Black, 12 Oz.

Perfect for sealing up any opening on campers. I had to recently add some 2AWG cables, for my 50 amp DC/DC charger system, that needed to be plumbed from inside to the frame. I removed a portion of the factory sealant (that looks identical), fished the cables and once set, resealed. I especially liked that it allows the hose to be cleared, making it reusable up to a certain number of days. This came in handy when I had an another project and needed to use the can again, a week later.

Worked great. Can't find black locally so this was very handy. Would order again.

Easy to work with, dries in 15 minutes. After 8 hours you can cut off the excess. I needed it for it's adhesive quality and it's perfect. The color is great and blends in. Once you start using the can and straw, you have 30 days.

This is black expanding foam.It dries pretty quickly, it's easy to use. It doesn't expand a lot, but it filled all the holes i had to fill.

I’ve spent my life as a building superintendent, have tried many different products, this one is best for rv’s because of the weather penetration as you move down the road. Just follow directions and the few tips I share. It’s perfect for Rv gaps around underbelly and wiring holes. I cleaned all surfaces with 91% rubbing alcohol to prep surfaces and help it adhere. The one review that said it didn’t stick, he probably didn’t prep surfaces or shake it well. I also heated up the can by soaking it in hot water before applying.It expands more than one inch, more like 2” (maybe because I heated it up?) Says it is for exterior applications, once it cures you can trim excess if you like. I was impressed how far it covered. Went all the way around my 40ft 5th wheel. Just a warning, wear gloves, this stuff is sticky and doesn’t come of skin or clothes.I bought another one to seal all piping as it penetrates through the floor and to go into basement to seal everything else up in there. Really love this stuff, it’s a great product and I highly recommend it.

great foam spray! thick black! hardens fast! compactable! stays black and is paintable!

Works great, but please don't be a dummy like me and ignore the bIg bold message on the bottle to ALWAYS USE GLOVES. I failed to heed the message and the stuff is not coming off my hands even after using nail polish remover. Save yourself a headache and use gloves because this stuff can be messy.

Does the job, but with in a short amount of time, it turns orange! So disappointing. This is at a Kio pond area, ai wanted it to stay black.
