Use as part of an easy two-step process to repair scrapes, chips and gouges in plastic and aluminium surfaces. Eg. plastic guards, covers, fairings, aluminium painted boat hulls. First, prime the surface with a thin layer of Mega Fusion and allow to dry. Then apply a top coat of either 9 Second Chip Fix or Hairline Fix or both (depending on the type of damage or amount of gloss required).Can also be used as a powerful adhesive. Eg. to bond two pieces of plastic together.
