camera case exhitbiting sticky substance

I had a similar problem with electronics and found an answer that seems to work well.

1. Clean the item as well as possible without damaging it with water and a single drop of Dawn or similar detergent. I found that a clean paint brush dipped in the water, shaken out, and aggressively brushed in the nooks and crannies worked well. Put a lot of effort into getting it super clean or dust and such will show up later. Let it air dry completely.
2. This will be sprayed with aerosol shellac. Cover for painting using blue painters tape, rubber hose pieces for knobs, popsicle sticks/wooden matches/toothpicks/skewers for electronic connections.
3. Spray with aerosol shellac using light coats until covered.
4. Optionally if you want a matte finish (this helps hide any imperfections in the rubber) use clear Rustoleum aerosol matte.
