Abstract
A method of inspecting the surface finish of a component comprising providing an original surface to be inspected. A release agent is applied onto the original surface and an epoxy mixture is applied over the release agent. The epoxy mixture is allowed to harden into a replicated surface. Once the epoxy mixture has hardened, the replicated surface is removed and a metallic coating is applied thereon. The coated replicated surface is then ready for inspection.
