Dip Masking for Hardcoat Anodize 2004. Q. I am a Sales Engineer working in the Anodizing Field. I am working with a customer who is doing Hard Coat Anodize. We are looking for a product to dip the parts in to mask & then cut away what area we need hard coat anodized. We tried one masking supplier, and too hard to remove masking (not an option).
