Hello. I'm Steve Smith. I'm the guy who invented Clear Penetrating Epoxy Sealer [also known as CPES], back in 1972. I've gathered up and organized quite a bit of information about it, since then.
I originally invented it as a solution to slightly deteriorated wood. It turned out it also was (I modestly assert) the World's Greatest Primer for paint or varnish on wood.
It is distributed by Smith & Co. under two names, CPES (above) and MultiWoodPrime. The MultiWoodPrime website
http://www.multiwoodprime.com/ has information about its benefits on new or sound wood. There is information at the main company website
http://www.smithandcompany.org/ about the product and its use in the restoration of wood. One of my distributors is The Rot Doctor, who serves the general public with Internet sales.
The underlying science of how it works is given at
http://www.woodrestoration.com/. There you can see time-lapse photographs,pictures thru microscopes, mechanical tests and even an open standard for this kind of product.
The information at those websites should answer a lot of your questions. If it makes new ones, just ask.
