catalytics are expensive.

use a nut splitter or a cold chisel to remove the rusty nut,then clean up
the stud's threads and use a new nut.If you can get a Dremel hand grinder
with a cut-off disc in there,that can start a nice cut for the chisel to
finish.
(back when Craftsman was tops,they used to make a nice set of thread-
chasers to clean up rusty/dinged bolt threads.I have a set for US threads.)

I suspect shops have air-powered chisels,making it a lot easier.
