Nice. I also just ordered some samples from paperandmore. Some white metallic paper and card, a sheet of the bronze (figured it would be good for exhausts). Also grabbed a couple of the silver wave sheets as it looked a little shinier/glossier than the pearlescent paper.
Can you post a picture of the printout on the silver paper? I want to see/confirm that I want to return the silver and continue just using the metallic white. I printed another page (Roman's F-104) on the metallic white, and it looks great.
