I think many epoxy vendors treat infusion as a buzz word.

I have vendors tell me all about their infusion epoxy with a 600+ cps. Seems ridiculous, or they are doing some other type of one sided infusion, perhaps.

Boatdesign has posts from years ago suggesting 300 cps is the max to infuse with, and i imagine less is more.

I mean, yes, i guess it is possible to do with thicker, but certainly as the part grows in size and complexity, where you are more pushing the limits, the low cps and longer gel.
