T-111 Siding over Tyvek HW

Siding my Horse Barn with T-111 doug fir siding.
Housewrap currently over plywood sheathing on the pole barn.
I plan on priming the BACK of all of the 4x10 T-111 sheets before putting up to protect them.

-Should I install Home Slicker from BenjaminObdyke to shed water and protect the T-111 siding even further.

-If I do install the Home Slicker, do I need to do anything at each vertical joint of the T-111 siding...I don't think so, but would like advice (i.e. if going over only housewrap, I would add an extra 6" vertical piece of flashing tape to protect the area even more)

I'm looking to do this the correct way and limit the maintenance on everything I do and extend the life of it.

Thanks for the advice!

Kind of overkill.
The t11 will last a decade with just a good coat of paint.

I would be concerned about any sandwich, too. Either a manufactured rain screen or 1-by strips at the studs would be my suggestion. I'd fear that if two sheets of ply are tight together the drying time would be more than you'd like. Lasting a decade they may do, but that is pretty short-lived. Shoot for 50-80 yrs. Why did you not use the Tyvek then the T-111 as the structural sheathing, perhaps w/ some metal cross-bracing?

Solar driven moisture, locations with high humidity, and 40-60" rainfall a year need a rainscreen system. Haven't used this link for over a year, and guess who it's from....LOL: https://docs.google.com/viewer?a=v&q...RvUBSlz4b5thmA

The joints are fine, just don't caulk them shut. Be very careful on the nail depth, breaking the wood fibers.....Follow the instructions.

17,000 dryer fires a year, when did you last clean the inside of the dryer near motor or the exhaust ducting?

How close to grade is it going to be?
That's what cause most if the trouble with T-111.
