Clean the parts as well as possible with a degreaser. Then for cracks, use a dremel to put a ''very'' small notch (a V-shaped channel) on the back side. Into that put a filling of the Plastic Weld, then a layer of fiberglass over the crack. Make it an inch or two wider on either side for good coverage. Then work more Plastic Weld through the fiberglass. | Clean the parts as well as possible with a degreaser.

The technical bit behind this is that the fiberglass just adds strength in a way that only a mesh grid can, and the Plastic Weld acts as a bonding agent that sticks to the fairing ''and'' the fiberglass. | The technical bit behind this is that the fiberglass just adds strength in a way that only a mesh grid can, and the Plastic Weld acts as a bonding agent that sticks to the fairing ''and'' the fiberglass. | ||
