Review on Maximizing Buoyancy & Thermal Protection with TotalBoat Urethane Density Flotation Insulation by Russ Charmin

Works as intended and I'm happy with the results. These two cans are expensive and only filled one end of my 50 year old canoe, but now I'm sure it will float if I capsize. The original foam has been eaten by chipmunks over the years. (Don't store canoes on the ground, kids). There was a little damage on the other end of the canoe and I used something great there. The company says it can't be used for swimming, but I had a lap swim in my pool for a week with no side effects, so....🤔. The photo shows 3 different fillings. Once it was in place I used a hacksaw blade to level it so I could reattach the aluminum plate with the rivets. Now I sleep better knowing that if my kids and grandkids use it after I'm gone, they'll be safe. My wife says I'm a little crazy when I draw flames on it, but it looks cool. 😎
