I used about 2/3 of a gallon on 1/2 of the hull (23 foot boat). I was amazed how well it worked. I would say it took of 90% of the bottom paint. I believe that what is still on the hull is only there because I did not put the stuff on thick enough, and or let it sit long enough to work.
I have found that where a very thin film of bottom paint residue is left, 800 grit wet paper takes right off.
