rust pitting in original 289 valve covers

[Dmon]

I finally found some original 1967 289 valve covers on eBay and bought them. They were as shown, but once I samdblasted tehm down and got off the correct blue paint, the navy blue beneath that and the red (RED) paint under that I found some areas taht have some bad pitting. It is a cosmetic thing - they are still oiltight and structurally sound but I'd like to fill the pits. Would bondo or glazing putty work for valve covers or is the heat too much? Or would something else be the way to go?

Please don't reply telling me to get another set. It took me 4 months to find these at a decent price, and it is very hard to find the smooth stamped steel covers with the D-hole for the PCV valve grommet. I already have 302 ones with the "Powered by Ford" embossed in them so they are not an option either. Picky ain't I? ;o)

I would hit them with some high-build primer, brief wet sanding of the pitted area, and a coat of Ford Corporate Blue paint. Been there, done that.
