prhousejr, the sealer is from the Eastwood Co. it's called brush on seam sealer. I used it on the floor pans after I scraped the factory stuff off and as you noticed, the trunk pan bump. It will not be as noticeable when I put the body undercoat on top of it. Real gooy stuff, but it WORKS. I know this because last winter I had the car outside for a week with 2 water resitant covers and a huge blue tarp on top of the other covers and it rained like hell for a few days. When I went to move it back into the garage , the trunk had 1.5-2 inches of water in the trunk, talk about water tight, I could not believe it.
