Question 50 year-old wood fence, what paint to use?

Hi all,
I've searched the archives looking for help but can't find what I need... I have an old farm in SD with about 200 ft of old wood fence, it was NEVER painted or stained. I am replacing a couple of posts that are rotted out at the bottom and some of the boards as well. There are lichens and moss growing all over it but I'm just going to paint over all of it (I know you're groaning). It faces south and gets direct HOT sun in the summer and -40 cold in the winter. I tried a gallon of oil based white barn paint and the wood just soaked it in and drank it like a dying person in the desert. Is there anything you recommend? Each section has 6- 2 x 10 boards and there are 20 sections. I was trying to use a trim roller and had modest success, though the paint I was using was garbage... So here are my questions:
1. What paint?
2. What method of application?

I look forward to and appreciate your advice!

Old untreated wood is always thirsty.

For paint you should prime with oil base and finish with latex. If it were me I would apply 2 coats of solid latex stain - less work and maintenance.

Any paint/stain you apply over fungus or dirt won't be any good. It may color it but won't protect the wood and will probably fall off shortly

The fence can be painted with brush, roller or spray. A roller would be the most diy friendly.

Thanks for the advice!

Well, I went to our local Ace Hardware... it was that or Wal-Mart , and I've had quite good luck at Ace. They said that with the amount of gunk on my fence and how thirsty the wood is, they felt that we'd have better luck with "Farm & Ranch Paint", also the fact that we might have livestock that might nibble on the fence... well, we got up before dawn this morning and got about 1/3 of it done before it started cooking outside. The oil paint that I'd put on the day before had turned pink (?) and the new paint seems to be covering everything as well as we could hope. We just wanted a cheery white fence to look at as we drove up. We might have to repaint it every year or two... but maybe our kids will have to do it next time!

Sometimes with oil base paint the solvents in the paint will disolve a contamiment on the surface - changing the color of the paint. When it happens with latex it is usually a stain bleeding thru that causes the color change.
