If they are already aluminized and you're not a bling-freak
then you may just want to touch up scratches and patches
of rust when they appear. I have had POR-15 high temp
"cast iron gray" on my manifolds for about a year now and
it's holding up really well. I painted them after porting since
I had them off. This stuff -likes- a light coat of rust for
adhesion. Just wire-brush off any loose crust and dab it on
with a little brush, says I. Not like Macs are all that pretty
anyway, if all you want is longevity put this stuff on the
outside and let the soot layer protect the inside
