Since there is no possibility of hanging so much weight on the panel to allow it to deform, and all aluminum alloys have essentially the same modulus of elasticity, select any conveniently available
Actually the flat faces on the panel are NOT just epoxy-glass - the strength comes from a piece of 1/8 inch / 3 mm plywood sandwiched between the glass layers. Best regards, Rob Housman Europa XS Tri
Well . . . I think that the factory got it right by reinforcing the panel with plywood (if it were not needed I doubt that they would have done it), but functionally 3mm aluminum (or even 1.5mm per F
Assuming that the product (with which I am not familiar) is sufficiently fine (on the order of one micron particle size) you should be able to polish to a specular finish with no visible haze or scra

Wow, I did not realize that I had such a reputation. Shot peening a metallic surface indeed creates a "skin" in compression thus partially countering any applied tensile load, which in turn makes the
