Got brave, did some "routing", with a dremel. As you can see, even with a template, my free hand isn't the best.
Trying to figure out if I want to put anything on the hatch in between the ones with the crappie and bass on them. Angled lines, 45*, something else?
Need to go around the hatches also, they're rubbing.
I did some scrubbing on the foam, in a couple test spots, the dirt came out.
