How do I paint the inside of my port if it's only 4" wide? I don't have the top of my box glued on yet while I find out how to do this.
I sealed my box with liquid nails, and I want to do the same with the top after it's glued onto the box. So I can only paint it after the top is glued on and sealed... but I don't have much room to move a can of spraypaint around inside the port. Can anybody give me some advice?
