Any suggestions regarding adhesives? What gauge aluminum do you recommend?Unless you plan on buying some large and, relatively, expensive equipment it\'s best to leave this sort of thing to professionalsI was a framer for many years and have had many a customer who ruined their artworks trying to save money by doing things themselvesHowever, if you really want to go the D.I.Yroute, I seem to recall that 3M was marketing a double-sided adhesive sheet that you, first, laid down on your substrate (in this case, the aluminum) then laid the artwork on top, smoothing it out with a silicon squeegeeNot sure how archival it was thoughEverything has to be absolutely free of dust or it will leave bubbles and other surface imperfections in your finished piece.Other related question
