RE: Coleman Bayside Alumi Tite Roof Problem - Help Needed
The issue with the aluminum Krystal Kote panels disintegrating from the inside out is due to electrolysis damage.
Where a weak point, (a small unpainted and exposed surface) exists in an aluminum panel that has any fasteners of a dissimilar metal, a galvanic reaction occurs. Unfortunately, aluminum is the lowest metal of the "galvanic series", and will corrode before any other metal.
I had the side panels of my 2004 GTE Niagara's slide out replaced under warranty back in 2005 due to the aluminum disintegrating, (due to the steel staples used to hold the plastic friction panel).
The Alumitite roof has steel screws holding on the Yakima rails which will eventually cause the galvanic reaction to occur at any weak spots in the Aluminum, (microscopic spots of bare unpainted metal). The original steel screws should be replaced with sealant/adhesive and aluminum rivets to attach the Yakima rails in order to minimize further electrolysis damage.
