Stephan-
Thanks so much for the detailed response! I use Micron Extra on my boat, and always have some extra on hand. Would the Micron Extra work same as CSC?

Funny you should respond to this, since the Aqua Tek wax I've been using for the past 20 or so years on the tubes was bought from Defender back in the day! I only wish they continued to make it!
