I got what I think was a real deal at TSC yesterday. they were closing out 6" x 10' cedar posts at $1.00 ea.I bought them all [170] for my retaing wall [see previous post "building retaining wall"].I'thinking that I need to fab up a soaking tank, 18" dia x 5' to soak the ends before I set them. I was thinking foundation coating , or ? for 10 hours or so to inhibit rotting. Comments or further ideas ?

In the previous post you talked about a 10' high wall.
Here you say the posts are 10' tall.
I think you are going to have a tough time holding up a wall with no footings, LOL.
Seriously, cedar is not a very strong wood, and not to rain on your bargain, but you will need to put those posts awfully close together to hold back 10' of dirt.
Other than that any good preservative will help.
Best of luck. ....

The section that needed to be 10'[flood protection] was done w/steel posts last fall.The remaining 300' needs only to be either 2' or 6'. I graded a lot of the bank down this spring so that the wall wouldnt have so much of a tunnel look.Also the wife thought bank landscapeing with a lower wall would look better.Now that some of it is done,I agree.I'm also going to open up the spot where the two creeks come together into a shallow pond of sorts to help lower the velocity at this point.I was also figuring on 2' centers for the cedar posts. ....

I bought a product called "Copper Brown" at Home Depot to spray on the underside of my shop. It is a serious wood preservative that contains strong pesticide/fungicide/mildewcide to inhibit rot with ground contact. I think it would be great for dipping. ....

If the cedar is below the water line, you really don't need to treat them at all. They will last 30 years in the ground, unlike other species. They will deteriorate in the ground in some areas. We use them for retaining walls on lakes and rivers without any treating. ....
