Filled some holes with resin/filler over the weekend. Now, as glass is, is colored "greenish". Some holes are located below water (where previous transducer was) and are only screw holes (maybe 1/4" is largest hole filled).
Question is this - does the glass have to be covered/sealed with something else prior to putting it in the water?
If so, with what? and how to make it look, well, not ugly.
