I was wondering how much paint to order to paint the cab, doors, fenders and hood? Two gallons? Jim Carter is having a 10% sale on now.
I bought a gallon and a quart and painted the cab, fenders, hood, bed, and all the miscellaneous Omaha Orange bits. That was a WAG on my part, but I still have a bit left, so I think a gallon would fix you up.
The hardener to paint ratio is 1:15 as shown on the Tech Data Sheet, so that doesn't add much volume. You can thin if needed up to 10% with xylene.
