• Great sprayability
• Fast drying
• Superior corrosion protection
• Excellent adhesion to bare metal

 PREPARATION:

1. Clean surface with 3837( ) SEM SOLVE.

2. Sand with 80 grit paper. Surface must be bare metal.

MIXING: Shake can vigorously for one minute after mixing ball begins to rattle to ensure color uniformity and to prevent clogging. For best results, use only when can temperature is approximately 70°F (21°C).

APPLICATION:

NOTE: Remove any excess 40783 prior to applying any plastic filler, otherwise lifting will occur.
