Kip, I mean no offense and I am sure your intention is to help, but if you're not sure of something or you're relatively new to diving you should offer an opinion and not make statements as if they are fact.
The suggestion to use a skin under a wetsuit is great if you are a beginner who has trouble putting on an ordinary lined wetsuit, but for high performance open cell and coated suits the use of diluted conditioner is what works. It is also the standard for tens of thousands of experienced freedivers around the world. The use of a skin will not work with these suits.
Nice to have you aboard here at deeperblue.net!
