ABSTRACT:
A method is disclosed for coating rusted matallic surfaces which comprises (a) removing loose rust particles by superficial surface treatment, (b) applying a coating containing about 55-95% by weight of an aliphatic(meth)acrylic monomer having at least two sites of polymerizable unsaturation and having a 25.degree. C. vapor pressure of no greater than about 0.5 mmHg and a 25.degree. C. viscosity in the range of about 3 cps to about 100 cps, about 0.5-5.0% by weight of a peroxide curing system and about 5.0-35.0% by weight of a drying oil-based oxygen scavenger system, and (c) allowing the coating to cure under ambient conditions.
