Can you use wax with the XC110 process?  120 degrees isn't too hot for wax?

No you can't, it is too hot. Even most 'high temp' waxes will only handle ~80°. 

There's no need for it, chemical release agents work superbly.

Semi-permanent release agent vs wax
mporta71 - 5 Years Ago
     I use wax for surfaces that have some level of porosity (like body filler) and surfaces that are not resistant to solvents. Usually permanent releases for everything else even tho we started using...

             Thank you

     It's not always one or the other. I use semi permenant release agents on all my moulds including the ones I want to use wax with. Semi perm and then wax on top too.

                 The semi permenant gives the mould a safer release and the wax allows you to spray gel coats on to the surface as well as making for a better gloss mould finish. I use this on moulds requiring wet...

                     Understood, thank you!

     The reason why wax is better as the top coat (or only release coat) for wet lay up and where gelcoats are used, is that semi-permanents can make the surface so slippery that thick gelcoats end up...

             Thank you for the additional advice

             I'm quite new to semi permanents (Zyvax) and I have been giving the mold a single coat top up after each pull...as much as because I will lose the Zyvax to age as anything. You would need to do a ful...

                 I do exactly that, just keep coating on top. You can even change the release/slip with the different grades from Zyvax/Chemtrend.

                     Cheers...But do you clean the wax off first before applying a new coat?
chriscnf - 5 Years Ago
                         For a pre preg mould I use only semi permanent release agents and would continue to add more semi permenant coats. For a Semi Perm and Wax mould working with wet layups I usually continue to add...
