This is probably based purely on experience but I have to ask to start somewhere. I will be epoxy priming most of the panels soon and trying to get a sense of how much a single panel takes to cover. I would assume a door on an e-body is about the same as a fender or quarter section. I would also assume a hood is about twice the size. Can we agree on this to start. Simply sizing panels relative to each other. So lets use a door as a base. How much would you use to lay down 2 coats of epoxy primer on a single door? Just the outside of it.
I am only trying to get a base appoximation. Don't want to mix a quart when I needed a pint. I hould be good to go once I start shooting each panel and seeing how much I use, but trying to get some info first shouldn't hurt.
