Looks beautiful! Make me want to pull my 1/60 outta the closet I started a year ago. I'm not so sure it's needs a dull coat. It looks like the flash from the camera is bouncing back pretty hardcore. I know with my camera I have a hard time representing colors as they truly are.
As for the weathering, I sorta like the clean "toy" look. I've seen to many toys that are weathered and panel lined and they are just too over done. Now, if you can work some magic like jung, Anasazi, or WM_cheng, by all means go ahead.
