Weatherstrip Drip Rail Push Pin Retainers
Tip:

1. The part and surface should be 21°C (70°F) prior to installation. The vehicle should

remain 21°C (70°F) for one hour after assembly to allow adhesive to develop
sufficient bond strength.

2. Use a J 25070 Heat Gun or equivalent to remove the old weatherstrip. Clean all

adhesive residue from the door opening and wipe the surface dry with a clean lint-
free towel prior to installing the new weatherstrip.

3. When removing protective liners from the adhesive backed weatherstrip, be careful

not to touch the tape with hands. Do not allow the tape to come in contact with dirt or
any foreign matter prior to adhesion.
