Yes it is possible, plug all nuts, w/silicone hi-temp plugs
and cap all threads on bolts or studs. You do not want
cured powder on the threads. If they lightly blast before
the iron phosphate and make sure they are completely
cured, they will hold up fine.
Buy a small container of touch-up paint that matches.
That way when you are tightening them down if you
scratch one you can touch it up. They are kind of a pain
because you just added 1.5 to 2 mils all the way around.
That makes it larger exponentially. And do not do any
screw heads.
Good Luck :smile:
