How do I mount photographs on sheet metal?

I need to flatten and mount 40x60 fiber based photos on sheet metal. What are the steps to this? What do I need?How do I mount photographs on sheet metal?
I wouldn't use spray adhesive... I've had a lot of experience with it, and it just doesn't cut it in the long haul - especially on a non-porous surface. They recommend you spray both surfaces for a permanent bond, and it's murder trying to position a piece that big without re-positioning it (which you can't if you've sprayed both surfaces!). Even the industrial stuff lets go at the corners. I wouldn't waste my time with it on a piece that big.





I still think your best bet is an adhesive film. Did you call Seal Brands? I still think they'll have the right product.How do I mount photographs on sheet metal?
industrial adhesives... e6000...


or possibly some spraymount like the craft 3000 glues or similar...








cheers!
