The product is very viscous. I put my tube in the sun for an hour and had a great glow. Sealed the bed of my Nissan 83 truck from the bed liner. This pipe made the entire bed including the wing niches and I have little left. I wasn't sure it would cover that much, very glad it did! Perfectly sealed, the spray on the feed stuck to it perfectly. VERY satisfied, got a professional job at a reasonable price!
