Disclosed is an adhesive composition having a pigment grind of 0-2 mils (0 to 0.05 mm) measured by the HegmanØ guage, said adhesive is sprayable at a total solids concentration of 25 û 2 wt.%, has a viscosity of from 50 to 500 cps (Brookfield LVT 2 @ 30 rpm) and comprises a nitroso compound, filmforming halogenated polyolefin, acid acceptor and from 5% to 35 dry wt.% of inert, incompressible, spheroidal particles having a BET surface area of from 0.1 to 10 m2/g and a 50th percentile particle diameter (D50) of 5 to 25 èm. Also disclosed are a rubber-to-metal adhesive which comprises a plurality of microspheres wherein said adhesive having a weight percent concentration of at least one percent of the microspheres and a viscosity less than 500 cps (Brookfield LVT 2 @ 30 rpm), and a method for spray applying the rubber-to-metal adhesive composition which comprises spraying onto a metal surface in an amount to provide a dry film thickness of from 0.0003 to 0.002 inch (0.007 to 0.0508 mm) +/- 0.0001 to 0.0003 (0.0025 to 0.0076 mm) in one or two sprayed layers.
