METAL-MASTER is a premium, self-sealing waterborne pre-catalyzed coating designed for the toughest of situations. METAL-MASTER can be used on most metals and plastic and adheres well to powder coated finishes. It dries to a film that is hard enough to be buffed to a mirror finish yet maintains its flexibility. Ease of application, hi-build, and quick dry-time are properties built into this unique finish. Application: METAL-MASTER is designed to be sprayed although on smaller pieces brushing is done very successfully. Stir gently so as not to create air bubbles and then strain. Do not over-apply. Thin coats are better than heavy coats. Product should not go on looking milky. If it does you have applied too much and dry time will be lengthened substantially. Dry Time:METAL-MASTER is designed to dry to sand at 75 F in less than 20 minutes. Re-coat immediately after sanding. It is safest to apply no more than 2-3 coats per day. Product must be completely dry before another coat is applied. Maximum hardness occurs after 7 days.
