The "infusion" process has been used for several years by other boat manufacturers. I think J was the first to start using it mass production, they called the process SCRIMP. I heard that part of the reason they went to it was b/c the office of environmental management was requiring them to lower their VOC and HAP emissions. However as an added side bonus, they got a stiffer lighter hull with fewer voids that was less prone to blistering. I could see PC using this process for their boats in an effort to reduce their VOC and HAP emissions as well, esp since they are in CA.

Interestingly enough, the core has TONS of small holes in it that were designed to let resin through. They called these "resin rivits" It help join the three layers of material and decreases delamination. I would suspect that it's pretty similar to the process the PC is using.

Here is a short little bit on it: http://www.jboats.com/j109/j109scrimp.htm

Apparently, they could tell you the quantity of resin in a J109 hull down to the teaspoon!!!
