Masking/Stop off for anodizing on complex parts

RFQ: Hello, We pretty regularly have complex aluminum parts with a lot of features (slots, threaded holes, bores, spot faces) that are chem filmed then anodized (either type 2 or type 3). We use a various methods to mask these products like silicone plugs and tape to cover pockets from lacquer stop off prior to dipping to help clean up then modified soldering irons with metal templates to achieve very clean and precise masking. Some features are very time consuming to plug like a series of small holes in a part that the customer wants protected from anodizing. I'm curious if anyone has found a liquid silicone product or similar that can be applied by hand, injected into these holes, trimmed once is dried, and easily removed after plating. I'm Also interested in any type of ground breaking stop off product. We are manufacturing very precise, geometrically complex parts, generally in low volume. Essentially any leaching or chemical entrapment could/will scrap these parts especially if the process is hard coat.
