Bond, not to sound like a tool or anything, but that just doesn't look very convincing. I would recommend putting some aluminum sheeting on the front and spray painting that flat black. That way it doesn't just look like some plywood with paint on it.
Plus, it'll look alot better with the sheeting bolted on the shield. Here's an example of the Pedonidas shield up close.
Another example after all the painting was said and done.
See what I mean?
