Chuck is right, but pits can also be filled.. JB Weld is one suggestion. It
can be sanded perfectly smooth & painted over. You can also try using some
auto-body spot filler, though I don't know how tough that is.
tough enough that it is sometimes used for auto-body spot filler!
Bondo is durable.
Fenders lead a rough life.
But, the purists insist that all auto-body spot filler should be done
with lead. Very similar to the way that some of us insist that any
replacement parts of a classic somputer should be exactly the same as the
original, perhaps down to with period appropriate date codes.
Painted over?
On something that was originally bare anodized or galvanized?
I like the "crackle-coat" paint,
but you could paint it pink and purple, like a "repurposed art" 026.
If the rust pits are deep, you can use muriatic acid to clean the rust out
of the pitting before you fill & coat. Make sure to follow-up any muriatic
use with some phosphoric acid.. else it's going to flash-rust like mad. If
you don't have a bottle of it, RC Cola is a cheap & available source of
phosphoric.. yes, it's low concentration, but it's enough to do the job.
In most places other than the south and Chicago, Coke and Pepsi are what
is used. I don't think that SNL (Saturday Night Live) ever did a "No
Coke; RC" skit.
