Clean and Dry the Surface Before Sealant

This metal is [oily/wet/coated]. What surface prep and cleaner does the approved sealant require before I apply it?

Sealing, Leakage, Mastic & Pressure Testing 1st Year GREEN

Watch out

Do not smear mastic over condensation, dust, cutting oil, or loose coating and expect thickness to make up for poor adhesion.
