I tried to search? didnt really find what I needed. So...do I need 2 gallons of black urethane single stage to completely paint a pickup? thanks

Probably, if you're gonna paint everything, jambs and unerside hood, etc.
Thing is, you'll definetly need more than a gallon and most brands price it
to where 3 qts is the same as a gallon.
You'll need more than a gallon, and should want a qt left over for future
repairs, so I'd figure 6 qts to paint it, and 1 qt to save (7 qts)
which should price out the same as 2 gallons.
Check your brands pricing and see.
Also it's better to plan on the high side, in case of mistakes and redo's.
A little extra left over, well,
everyone can use a some black single stage once in a while.

If you still want to buy less, buy a gallon and paint the bed,
since it's seperate anyway.
Once done you could easier estimate how much more you need for
the rest

It all depends on your prep. Is the truck blowed apart or all togethet and just looking for something to clean it up a little? If the bed is still on, doors still on, etc....then 6 quarts would be more than adequate. But if it is blowed apart and you are going to paint inside the bed, jamb it all out, underhood, etc. then I would go with 2 gallons and have a quart or so left.

I am surprised nobody asked what the mix ratio was for the ss you are using.

I would say that if you are not going to color sand, you just need 2 good coats. And you should be able to do that with 8 sprayable quarts for a full-size pickup. Spraying the inside of the bed too? Probably a little more then.

If you are using a 4:1:1 ss, then you will need 2 gallons for sure.

You might get by with a gallon if you are using a something like a 1:1:1 or a 2:1:2 ratio.

I'm pretty sure the mix is 4-1-1 for 1 1/2 sprayable per. Will be painting a paintless pickup with economy urethane and not a custom of any sort. The cost difference between auto enamal is way too small to ever justify using it.
