Roofing tar would probably be a more cost-effective alternative to what I used. Permatex makes both asphalt based undercoating and rubberized undercoating under different part numbers as shown below. I used the 80072 version. Both are messy to use, so wear disposable nitrile gloves when spraying.

Thanks!!
Sika Epoxy fence post sealant. It looks like some ready to use others are a mix.
For full transparency, I ran out of the Permatex asphalt undercoating with two fence posts remaining, so I decided to pick up a can of the Rust-O-leum rubberized undercoating at WalMart instead of waiting two days to get the Permatex from Amazon. The Rust-O-leum undercoating was much less viscous than other brands of rubberized undercoatings that I had used in the past. It seemed to penetrate into the wood grain as well as the asphalt undercoating and has not peeled a year after installation. It is nearly half the price of the Permatex undercoating if that is a consideration.
I used Postmaster posts. https://postmasterfence.com/
For the larger gates, I used coated steel square tube (4"x4"). Over concrete, like the entrance to our breezeway I used custom variation with a plate at the base of the postmaster for bolting to the existing concrete. Steel is enclosed in cedar, not visible.
Eventually may corrode. I'll be gone.
Even re-coated ground contact posts don't last around here. The best luck I've had with wood are the round green farm fence posts.

Like I said I have many posts that have been in the ground since 1999 and still have the undercoating on them...
I wonder if this product works. It claims a 20 year guarantee: https://www.postsaver.com/en-us/products/fence-deck-and-pergola-post-protection/

The best thing I have found for fence posts is Henry Wet Patch Extreme Rubberized - https://www.homedepot.com/pep/Henry...46kauT92IcVNfp9YhnDgCmd3Ecg1vgwgaAjNfEALw_wcB
.9 gallon. Hahgahgahgaha sorry.
expanding foam is food for the little bugs, some call them silver fish, they are little bugs, that are silver........not sure what the actual name is.
True enough since they make the anti bug stuff
I like that idea, However is Rubberized Undercoating ok ?
After 2 years, the rubberized undercoating appears to be wearing off the post quicker than the asphalt undercoating. In hindsight, roofing tar sealant would probably outlast either type of spray undercoating.
