Coating compositions comprising alkoxymethylaminotriazines polyols, and polyhydroxy oligomers which are useful for low temperature cure are low, in viscosity to allow ease of coating without the need for appreciable amounts of solvent thinners, and provide coatings free from the problems of crawling cratering, pinholing and "orange peel" formation. The alkoxymethylaminotriazines are preferably alkoxymethylmelamines. The polyols are polymethylol cyclohexanes containing from 2 to 4 methylol groups. The polyhydroxy oligomers are polyesters or acrylic resins. The compositions may by cured in the presence of acid catalysts in the temperature range of 70 to 105°C.
