Hi.
Can anybody tell me why not to use plywood for exterior clapboard siding?
I have riped 3/8 ply into 4 inch strips for a three inch exposure, with a 10 deg bevel on edges,
back primed, and hung with hot dipped galvinized nails.
I did this because i am building a Victorian playhouse and could not get any 3 inch exposure siding unless i ordered 800 feet.
Then i came across a product that was basically ply wood ripped and said hey why not.
So if u have any thoughts let me know thanks.

That should work fine on a playhouse. I have seen a lot of T-111 siding delaminate, so you should be prepared to see the same if the paint is not well maintained. Plywood has so much flat grain that it tends to shed the paint off as the wood expands and contracts. Some of the real wood products are so poor now that the plywood may actually be superior.
If it's already done, it's kinda late now.
Any Wood Clapboard can be laid at 3" exposure.
If the plywood is exterior grade, you'll probably be OK if you keep paint on it. For a playhouse, my concern would be slivers in the little ones.
