Roof rack on fiberglass hi top
So Iíve built a cargo rack that goes in hitch receiver . Turned out good. Weight tested with myself and other people jumping on it seems like itís road worthy... needs a can of Bedliner paint sometime soon and also dot tape reflectives and more than likely one of those bolt on hitch stabilization brackets.
The next project is a roof rack.
Bolting through the hi top fiberglass and going to have a steel bracket then some padding or liquid nail, maybe some kind of gasket material. Then the fiberglass shell . Backed with an aluminum plate or wood.
Basically the brackets for the roof rack. Gasket material. Fiberglass hi top . Gasket material . Back plate. Then on top of that Iíll be using 2 lock washers , 2 washers , 2 rubber washers and a lock nut for each through bolt. I havenít drilled a hole through the shell yet and am kind of hesitant to do so ... donít want cracking or anything else to happen over time or something more serious like a solar panel flying off at hwy speeds ...
so any suggestions as to through bolting fiberglass .... would be appreciated . Thinking 2 bolts through side and one bolt holding down the brackets . On each bracket.
