Looks like about 4-6 minutes is the sweet spot for UV exposure. I also took the developer up a notch by adding almost twice the amount of Sodium Carbonate and by heating the water before hand.

I'm thinking I'll try stripping the board I made earlier with some Sodium Hydroxide and re-painting the board and trying again.

Would sodium hydroxide strip the copper layer too? I'm guessing it might oxidize it heavily and leave the board unusable. Otherwise I'm gonna have to get more copper clad boards.
