ABSTRACT:
An adhesive-free, dry, free-flowing powder composition suitable for use in surface defect detection, where the powder composition comprises a physical mixture of particles of a colorant and particles of an extender, which mixture includes particles of colorant and particles of extender each having a particle size of less than 100 .mu.m. The powder compositions of the invention provide a simple, effective guide coat which readily highlights surface imperfections, such as scratches, orange peel effect and dry over-spray without the need for solvents. Also, there are disclosed methods of using such a powder composition to detect surface imperfections, an apparatus for applying same, a device for refilling such applying apparatus, and coated surfaces formed thereby.
