Rattle Can or POR-15 firewall

[frankdatank01]

What to do with the firewall?

Should I just sand and rattle can the firewall or sand and POR-15.

I plan to tear down and paint the truck down the road (much, much later). For now, I am just rebuilding the front end and engine to get it back on the road.

The truck is black over the original orange with white top and sides. I like the black but wish the PO would have stuck with the original. I like the color.

Here is a picture of the firewall. The PO tried to paint it with everything in place. Not much prep work. It was flaking so I hit it with the pressure washer when I was degreasing the front frame.
