Pneumatic Staple gun and staple recommendations

I am looking for recommendations on Pneumatic Staple guns (air compressor and gun) and staples (metal verses composite). I will be fastening 6mm marine plywood to frames. Two layers of plywood stapled with epoxy. 
 

 

 

I'm sure there are a few Forum members here who are familiar with the tool you're asking about though likely not because they've used one for the stitch'n'glue assembly method these CLC designs feature.

Maybe posting to http://forum.woodenboat.com/ will return results more to your satisfaction? The topics discussed there cover a wider range of fabrication techniques like the "cold-molded" method your description brings to mind.

(My exposure to pneumatic stapleguns is limited to the years I built trade-show displays.)

Don't do staples but my nailers are all Hitachi. 

Are you planning on removing the staples?
