I recently was gifted a session at a Board and Brush establishment, and made a lettered sign which I wish to hang on the garden fence. I would like to preserve it with a waterproof topcoat. Suggestions for product? The board was stained first, then painted, then lettered. I don't want the waterproofing product to alter the result. Thanks for assistance!
The lettering is flat, no 3D. I wonder if spar varnish would be a good option. Am a little leary of chemicals/health issues with auto clear (that I read in some other forum).
