I'm having two aluminum racks made to mount on the roof of my van. Each rack will hold two 100 watt panels. The roof is a Fiberglass topper with wood reinforcement.
I am using the 2 racks to be able to mount all 4 panels and tilt them as needed. The fiberglass roof is very uneven on top and will require varying lengths of "legs" under the racks to make the rack level with the ground. out of the 8 legs total (four per rack) 1 will be 1 1/2 inches, a few 2 inches and the worst is 3 inches. The mold the roof was made in was far from perfect!!!
I will be mounting the flat bottomed legs to the fiberglass roof with bolts thru the roof and wood reinforcement. I will put dicor between the leg and the roof and on the bolt heads and all around the leg.
The question: Do I need to buffer connection of the aluminum leg and the fiberglass roof. I thought a cut-up inner tube as a gasket in-between to keep the metal from wearing into the fiberglass. I would cover all the rubber with dicor to keep it from being exposed to the sun.
