On my 12 year old Ugly Stik I built a solid front...

I've never touched it once. If the tank's set up right, and not in a position where the lines are rubbing against the firewall, or anything that might jeopardize them, or the tank....you really shouldn't have to mess with it ever.

If you're going to do a hatch though...use screws. Screw magnets.....ba-doom-ppsshhh!!
