What is the proper procedure for preparing an oxidized, dusty asphalt surface before applying asphalt sealcoat?

1. Apply a thick coat of motor oil to soften the dusty surface aggregate.
2. Power blow, sweep, or pressure wash to remove all loose dirt and debris.
3. Spray clean water and immediately squeegee sealcoat into standing puddles.
4. Cover the dust with dry silica sand before spraying sealcoat directly over it.
