OK, I just built a fence out of pressure treated wood (the crap from
Home Depot which is not redried) a couple of weeks ago. It's an infill
type fence using the rough hewn dog-eared slats cut to about 5-6 feet
long held in only at the top and bottom, no middle cross beam. Anyway,
within several days huge gaps developed between the slats, presumably
as they dried. I can deal with that. What I can't deal with is warping
and twisting, which has also happened.

My questions to you guys with pressure treated wood experience:

1. Can I avoid shrinkage, warping, and twisting if I use special
pressure treated + redried wood and immediately stain it, or does
redried wood also shrink and warp to some extent?

2. Will I avoid shrinkage, warping, and twisting if I use the non
re-dried wood from HD and immediately seal it (even though it's wet)
with sealers approved for immediate sealing, like Wolman's "raincoat?",
or will it still shrink etc?

Thanks in advance
