Tony, I have a CAV s/s monoque. The first thing when I found out that my 40 leaked like yours I bought aluminum colored silicone glue. I forced it into every space that I thought water could get into. It worked great and it is the same color as the stainless steel. I also wiped off the excess to make it look neat. Then a guy in Nashville Tenn. washed and waxed the body with Griot's Speed Shine.
www.griotsgarage.com It is a dry wash. You spray it on a small area and then carefully wipe it off then buff it by hand with a soft cotton cloth. Two people and 15 minutes you are done. If you must use soap and water wash it from back to front. Now for the big hint which a friend put me on to. Use an air compressor with at least 100 psi to blow all the excess water out of all the crevices. It really works great under the front and back clips. You will be amazed how much water that will not be present to run down and leave water marks after you think you are finished. Joe [img]/ubbthreads/images/graemlins/smile.gif[/img]
