Exhaust Manifold Reconditioning

[CamarosRus]

To the above CERAKOTE Users............

1) How did you prep, media blast before applying

2) Someone said not to fire up a new/rebuilt eng on newly CERAKOTE'd
manifolds.........Does this mean I should use another set of uncoated Manifolds
to Break In eng and THEN change out the CERAKOTE'd Manifolds.........Lots of extra work..........

For #2, I ruined a set of jet hot coated headers years ago because I did not heed their warning. For manifolds though, there's a lot more mass, so likely won't develop the hot spots associated with thin wall headers and may be okay. IMO, either put in the extra effort or roll the dice...I prefer not to roll the dice.
