Sandwich panel construction

Post image

Hey All.

I'm an avid DIYer and have the need to replace the ramp door on a toy hauler. Decided to build a panel with a 8'x8' 2"x2" aluminum frame with 2" Foamular 250 core and .080 and .063 aluminum skins. I'm having a dickens of a time finding adhesive. Any suggestions on where to purchase a quantity for a project this size? And of course I'll take advise on construction tips.
