I know this is an old post. read this and had to join to add my two cents. you can weld trough cured (3-4 days) POR-15, like a weld-thru primer. you'll have to recoat to cover your weld, but if you got a good ground, weld away. keep it cool, as usual, spot welding is best, and you wont burn to much paint away.
