Take lots of rags and a plastic trash bag to dispose of them in. The HD Easy Off Oven cleaner does not drip too bad, the foam is pretty thick and after you leave it set for 15-20 minutes the anodizing comes of when you wipe it down with rags, you may need to hit a couple of spots twice. There are some U tube videos on removing anodizing from aluminum you may want to watch in advance. I had all the fiberglass surfaces covered with a drop clothes but its not too messy of a job. But like I mentioned I had a glob of the foam land on my arm and before I could get down the pier to the house to wash it off it burnt a nice hole in my arm so try and keep a hose or fresh water near by just incase and safety glasses are not a bad idea either, good luck Mike
