I would not recommend painting over the gray. I will post here but be done to flatten it. Something can be sprayed over it. To make it look older. Sent from my iPhone using Tapatalk
I like the addition of the rivets on the corners of the frame. The gray paint I used on the lower box is the RAL 730 and only comes in a gloss. The seed trays come in there raw form and do need to be trimmed with rounded corners. Thanks for posting this thread. Sent from my iPhone using Tapatalk
The corners of the tray should be rounded off, great start! Looks good!
I would recommend a repaint with the battleship gray color in a matte or satin finish. Right now your pack is looking a bit glossy. Also you could get a matte clear coat and spray the entire pack before weathering.
