priming exterior oil stain for latex

I need to repaint a section of siding with what appears to be a solid oil stain, which is next to impossible to obtain. So I guess my next best option is to prime it with something and then cover it with a latex paint or solid stain. There are multiple products available, none of which I have experience with. Some won't accept a stain topcoat, only paint. Here are a couple that vary widely in price. Any advice/recommendations for this kind of job?

You don't use primers with oil or latex stains.

Fine then paint but it has to be primed because I can't get solid oil stain.

I would recommend you go to a PPG store and ask about Proluxe stain (formerly Sikkens Rubbol stain). You don't prime when using stain. You will probably be sorry if you use paint.

How old is the current stain? Once it's weathered a few years, oil based products outside tend to cover with latex products without an oil based stain in between.

I've never had any issues applying a latex stain directly over clean weathered oil base stain.
About the only time you'd use an oil base primer under stain is when it's a light colored stain and there are concerns about tannin bleed.

Define "weathered". Paint stores are telling me they still recommend sanding but I'm not terribly interested in sanding large areas of siding

weathered = faded, no longer longing fresh
As a rule I don't sand siding although I do clean it first. Usually just a bleach solution but with what you have [or an extra grimy house] I'll add TSP to the mix - rinse well.

I don't see any evidence of fading but its a light colored solid stain that has been on for at least 10 years and at over 8000 feet you can be sure it has seen lots of weather and lots of UV.

At 10 yrs I would have no concerns with applying a latex or waterborne stain over it.

The plot thickens. I've been getting bubbles where I've prepared and restained using the original oil stain. I happened across a real painter and he came by and looked at it and said that linseed oil had been used at one time. He pointed out the big drips that I'd been wondering about (I assumed they had just glopped on tons of stain and it formed drip marks). These drips are still soft and elastic. You can see them on the lower edges of the half-log siding too. He said the old timers would mix the linseed oil with all sorts of stuff including other oils and stain, and suggested that the linseed oil (which he said never really dries) is the reason for the blistering and either stripping it (which will not be possible) or living with it are the options.

I was going to go with a water based stain for the siding but wonder if that is a good idea now. The problems on the siding that I need to restain are pretty small, but they seem to be caused by the linseed oil.

Yeah, a water based product over linseed oil is probably not a good idea. I'd try to locate an oil stain, no matter how hard you have to look for it.

Straight linseed oil never really dries that is why it's mixed with a coating or even just mineral spirits. Cut in half with thinner usually lets it dry ok. I to would be leery of apply latex over it. We used to add a quart of linseed oil to a gallon of oil primer for old bare siding that had been neglected.

This brings it back to my original problem. I can't get solid exterior oil stain.

Regardless of what stores you have locally, if you have the internet, you can get it. So please don't tell us you "can't."

Where I can get a custom solid color exterior oil stain that isn't gloss or satin since you seem to know.

Exactly what sheen are you looking for?

Here is one example. Most any real paint store, except in California, will offer a line of oil based stains. Overapplication of any stain typically results in more gloss and can lead to peeling.

agreed, stains have no sheen unless you apply it too heavy where it can't dry correctly.
