Clapboards suck ... they are a nightmare to hold a finish. Do not use HD'S Behr product, it will not hold up. Use Flood transparent stain and you cannot go wrong. They make a heck of a product. Go to their web site and check themout, you won't be unhappy. www.floodstain.com.
My buddy is a painter....he also says to stay away from behr products.....paint, stain or otherwise...one rule of thumb that he has told me ( and I happen to agree ) always spend the money on good paint, stain, ect...Benjamin Moore makes some quality stuff...you won't be sorry...otherwise you will be chained back to your house in a couple of years.

I used Beher (?) stain on a cedar fence. It fell off under the snow the next winter I went to Cabot oile based!
To answer your original question; Keep the base type of primer and top coat the same. Oil to oil, water to water....
