My 2015 305 3xpr3ss has 4 grady white rod holders in the gunnels. They are pitted and green. Why grady used such inferior quality ones I don't know most other hardware is top notch. Contemplating replacing them but they could be bedded with a tough to loosen caulk. Anyone had experience on replacing the gunnel rod holders ? Don't want to rip the gel coat getting them out thanks
