    Abstract: A coating composition comprises a crosslinkable carbamate-functional resin and an aminoplast. The aminoplast comprises the reaction product of an aldehyde and a melamine. The aminoplast has a content of imino groups of less than or equal to about 10 %, a content of alkylol groups of at least about 7 %, and a remainder of groups being alkoxyalkyl groups, all based on a total number of reactive sites present in the melamine prior to reaction. A coating system includes a clear coat layer that comprises the reaction product of the crosslinkable carbamate-functional resin and the aminoplast. Threshold adhesion strength, in accordance with MVSS standards, can be achieved between glass and the coating system when the crosslinkable carbamate- functional resin and the specific aminoplast set forth above are reacted to form the clear coat layer, while minimizing problems associated with high viscosity of aminoplasts having a high content of imino groups of greater than 10 %.

    Abstract: A method of painting a substrate coated with an electrocoat, wherein the electrocoat includes an average surface roughness equal to or greater than 3 microns, includes applying a two-component sealer onto the electrocoat to form a film having a thickness of from 5 microns to 20 microns. The two-component sealer is partially cured by application of heat to a gel content of from 10 to 50 wt. %. Thereafter, a topcoat, typically including a basecoat and a clearcoat, is applied onto the two-component sealer. Both the two-component sealer and the topcoat are completely cured by application of heat.
