Matches OEM foam on travel trailer underbelly
Had to replace waste valve on my travel trailer… had to open up my “sealed underbelly. Used this foam to seal underbelly after valve change out. Worked fine and closely matched OEM foam I disturbed and had to remove. NOTICE: you will most likely use both cans!There is a learning curve to applying the foam! Haha! Was a bit messy as I was laying on my back and shooting it in tight places.It wants to drip and drool!🤨 wear clothes u can throw away! Wear disposable gloves! Sticks to you and everything else! Drys reasonably fast. Similar to spray foam cans available in big box stores. However, none carry black color! I you want the OEM look… this works! I ended up using 4 cans total. Your job and skills may differ. Happy with results on my end.

Works well! although a bit expensive
I used it on a small/medium (2-4 foot high with 3 tiers) waterfall. It was barely enough for one. A professional would have used it with more efficiency i'm sure. WEAR GLOVES! If it's stuck on your fingers and nails, then a nail filer will help with the nails. Nothing but time will help with your fingers.

Worked ok but...
The rats chewed strait through it. I dunno if they died later on or what, but I guess the actual foam taste wasn't too displeasing to them to keep them from chewing through like I imagined it would. However, again, they may have crawled off and died after eating through it.

NO INSTRUCTIONS
No instructions I’m a senior citizen, female I would like to know how to use it. I get the idea, but I don’t want to waste my product on trying to figure out how to use it. It should be instructions on the can or in the box!!
