Using one of the brushes (Item 8, Table 3-3) or the plastic applicator (Item 11, Table 3-3), apply one even
coat of adhesive to the roughened surface of the tank and the prepared patch. The coat of adhesive should
be approximately 10 mil. (0.025 cm) thick.

Let adhesive set until tacky (approximately 5 to 10 minutes). Test by lightly touching one knuckle into
adhesive. Lift slowly. When knuckle lifts fabric briefly, and no adhesive is left on knuckle, it is tacky.
p.
Once adhesive is tacky, bring ends of patch together (adhesive side out), and position center of patch onto
center of hole (Fig. 3-3).
