The good news is that I've been commissioned to created a welcome sign for someone. The bad news is that they want it as an outdoor sign on 3/4 inch thick Curly Maple. I've done 1 outdoor sign in the past (for myself) and it faded horribly within the first 6 months. Can someone please let me know what finish or sealant or combo I should use to make sure this sign looks amazing but is protected and retains its Curly Maple glory?? All help is appreciated as always!
