This is why we should be pushing teenagers to have children.
Absolutely. We need to encourage our children to have children at about 16, and and have us raise them. Then, when they are 32, and actually ready to raise children, they can have their children do the same.
Why not just put down a resist layer directly and etch what the resist doesn't protect? That seems much simpler.
More simple, but processing that way wouldn't plate copper in the holes drilled for vias. It sounds like you're forgetting that step.
