the part gets heated then microscopic stainless beads are shot at it under pressure...its an incredible finish..i dont think its right for a top level resto..but close...if they have used the beads for a long time, or dont keep the machine clean it will be dull..looks almost like magnesium..its imbedding dirt..

i had an intake done and it was red..my intake went in right after 3 sets of rusty exh...manifolds...it transferred the rust to my intake...sucked..never could get the red tinge off..

you wouldnt believe what it does for cast iron..its absolutely incredible...you have to look around but its getting more popular..with the ban on chemicals ets..cheap too..</div></div>

Sounds like a variation of shot blasting.
