[quote=dmgbear55]On my 5.2 with the same spreader setup I also have a drain hole for that worst case scenario at the base of the mast. I cover the hole with some aluminum foil tape like is used in HVAC duct work. It seems to be impervious to UV and the day I need to drain the mast it would be fairly easy to puncture and drain without any tools.
If the top end of the mast is well sealed you should never have to worry about the spreaders. When you seal rivets make sure to not only seal the hole for the mandrel, but also around the edge of the rivet and whatever the rivet is holding down (like the diamond tangs).[/quote]
