Black Oxide Masking

Q. We have a vendor (aircraft) that is asking us to mask the outside, assorted areas on parts that are to be Black Oxide on carbon steel. This vendor tells us we should be able to mask black oxide is almost any situation. As of yet we have not been able to find such a material to hold up to the high temperature (300 degrees) Caustic solution.

1. Has any one heard of "Masking Black Oxide"

2. Does anyone have any ideas of a tape / something that would hold up?

A. Sir: Heatbath has actively pursued a stop off for our black oxide product group. We have not found a product suitable for consistent performance, yet.
