That look's a high class finish at silly money , makes me wonder about a similar finish on the aly trim many Zs come with ?
Have you had any other item's done ?
rollbars, door handles and dash with piano black finish (was wood finish), two years on still going strong.
I think quite a few other E85 and E89 owners have had parts hydrographics dipped in the past year (mac/neil had this engine done at the same place I used)
