Painted over rubber interlocking mats filled the gaps and waterproofed well
Flowed on good with a small roller need to coats in some spots where i put it on too thin but second coat went smoother than first

Not packed good
When item was received the inside packaging was barely enough to keep the can from rolling around. The can was dented on both sides and the lid was coming off. The only thing that saved it from spilling thru the box was the cellophane wrapping around the can. That would have been a gooey mess inside of the box! Product is very thick and kind of hard to brush on, roller did a better job.
