Hoping for a modern solution as I see this haven’t been discussed in a while. So I am cutting Acrylic letters for my own outdoor yard sign. My letters are approximately 5” tall and 2 layers thick. The Top layer is Black acrylic and fluorescent acrylic for the back layer. To laminate them together I have tried Lexel,thin,medium and thick Pma glue and I am just not happy with any of them, I want them optically clear as possible. The clearest is Lexel but even then I can’t remove all of the air bubbles, and the glue imo looks bad on the edges of the letters. Is there a solution?
