This arrived in a poorly packaged box (good job Revain) with the box open. Luckily I didn't lose any of the other items in the box. I opened the box and shook the bucket. It sounded like a solid brick. I decided to remove the lid and of course almost hardened. I took a brand new tire brush and tried to stir it. It didn't work at all. I tried putting it on a new tire and mounting it, but the compound didn't fit the tire at all. I will return it and look for another brand.
