Pot Metal Prep

[kencombs]

I use Kirker epoxy, primer, base, clear or single stage paints.   Not quite the coverage of the big boys but w a y cheaper.   Looks good enough for me.

 

That's current use, but I've done different in the past when we had a local 'wholesale paint' store.  Now that they're gone, only the parts houses have paint stuff locally so mine is all purchased online.

 

the only time I really worry about staying with the same brand is base and clear.   Otherwise I've seen no issues with changing brands after the primer.

Just a caution - I would be careful about media blasting pot metal.  I started to clean up an aluminum roaster pan (not thin metal) for my mom by glass bead blasting, but even being cautious with it (holding the nozzle back), it roughened the surface.  (This was, however, an industrial blaster, at the plating shop where I worked at the time.  There was no such thing as soda blasting, or other alternative media at that time, unless they just didn't use it.  We had glass bead & Aluminum Oxide.  There WAS another type of media used for cleaning gold & silver - not sure what it was, as I never worked in that department.)

I was going to mention that earlier and forgot to include it with my post.   IF, and a big if, I were blast any white metal it would be with walnut shell and start with lower air pressure, raising a little at a time until it just started to cut the paint.  Finer grades of glass or slag can be used, but it will leave a satin or coarser finish, depending on the metal and media.

For initial paint removal, with some old paint I have had success using a sharp razor blade to scrape the old paint off. If conditions are right, the old paint will peel off like snowflakes. It leaves a clean dry surface, and the flakes are easily vacuumed up. Be sure to wear a dust mask.
