A heat-sensitive substrate is coated with a first, low-temperature curing coating powder and a second, high-temperature curing coating powder. The time/temperature conditions of fusing and curing the low-temperature coating powder permit the substrate to retain its character and thus suffer no essential damage to the character of the substrate. The time/temperature conditions of fusing and curing the high-temperature coating powder would so damage the substrate if the high temperature curing coating powder were applied, fused, and cured, directly on the substrate. However, the coating provided by the low- temperature curing powder protects the substrate from detriment when the high-temperature curing coating powder is fused and cured thereon.
