Painting Quality Acceptance Standards?
Painting Quality Acceptance Standards?
"add standard reference or class call-out for the paint quality such as Class I, II or III. I want to include a paint quality class so the requirement is clear and parts can be rejected for not meeting the cosmetic standard."
I've never experienced a "Class I, II, or III" paint quality call-out. Doing a search here on ET I found nothing pertaining to "Class I, II, or III" either. If such exists, please point me in the right direction. I have a suspicion that what needs to happen is that our company writes and defines our own acceptance criteria, publishes it as a specification, disseminates it to vendors, and then refer to it on our drawings. But, I could be (hopefully) wrong.

You are judged not by what you know, but by what you can do.

Polyurethane should have no problems coating zinc......alkyds will saponify.
