A method of coating a sheet metal burner assembly base plate formed of a pair of joined overlying metal sheets having an integrally embossed air-duct formed therebetween is disclosed. The sheets are substantially entirely immersed in a slurry of ceramic frit and, simultaneously a volume of the, slurry at the exterior of the sheets is pressurized so that ceramic frit particles are forced into crevices existing between the sheets. The sheets are removed from the slurry and the frit is fired onto the sheets so that the particles driven into the crevices are fused to seal such crevices.
