Aluminum oil pan prep- coating the inside?

[BeaterGT500]

Looking for advice on the best way to prep a vintage cast aluminum COBRA T-pan for my 428.  It's an original "SSS" cast pan from before Branda started casting them.  It's pretty dirty from sitting around for about 45 years or so.  I thought it should be coated on the inside, since it's really porous.  I've never used one of these before, any suggestions on best cleaning methods?  Should I use the Branda oil pump pickup with it?

The original pans are designed to use the stock oil pick up . I don't know why the repro would be any different. You could use glyptal paint to seal the inside if you felt the need. Racers used it to seal the pores of the inside of the block so that oil would flow more easily back into the oil pan. https://www.eastwood.com/glyptal-red-enamel.html
