Important: If corrosion of the pinchweld flange is present, or if sheet metal repairs or replacements are required, the pinchweld flange
must be refinished in order to restore the bonding area strength. If paint repairs are required, mask the flange bonding area prior to
applying the color coat in order to provide a clean primer only surface. Materials such as BASF DE17(R), DuPont 2610(R),
Sherwin-Williams PSE 4600 and NP70(R) and Martin-Semour 5120 and 5130(R) products are approved for this application.
