I agree that it would be nice to have a correct list of finishes. It seems that Jerrys book and the list it is compared to when you search this site have conflicting info. One might say natural metal and the other says semi gloss black, or one says the jack is painted grey verses silver/gold cadium finish for example. Also does powder coating the subframe and front suspension in the 30% gloss look correct or do you need to paint as original? I am doing my Z10 and have seen them with white underside and most with black. Wish there was a universally accepted color and sheen chart and maybe suggestions as to what products others have used to achieve the correct look. This is a great site to learn from but everyone seems to push jerrys book, are all of his finishes accepted as factory correct? Thanks for all your help.
