Ive done the bottom cover on mine 5 times and it always leaked. This last time I tried "the right stuff" for the first time. No gasket. It comes out of the can kinda whipped up and tacky and doesnt want to smear smooth. I was doing it in the light rain and was sure it was gonna leak but Lo and Behold it didn't. It's a winner in my book. These days I clean the surfaces good so in the end no residue gets on my rag with when I wipe it with brake cleaner and of course get of the old rtv etc. off. I waited atleast over night but can't exactly remember how much longer.
