Prepare rubber by roughening with either a 24 to 36 grit aluminum oxide sanding disc on a slow speed sander or by stiff wire brush or carbide sanding tool attached to an electric drill. Clean the repair area thoroughly and degrease with a suitable, non-oil based solvent such as MEK, Trichloroethylene or Ethyl Acetate. |
