I recently saw an ad for Rupps Alum Guard wipes. It said that you can use it on the rails, hard top supports, reels etc. It would be nice to have some thing you could use on the hard top supports while you still have the side curtains on. If they are as good as they say, I would do a quick wipe down after a wet ride and a fresh water wash down. Has any one used them and what has been your experience? I checked the major boating chains around Annapolis and no one carries them.
