MG Chemicals dry film?

http://www.mgchemicals.com/products/416dfr.html I need to buy more negative dry film, and MG just came out with theirs. Has anyone used it? Their web pages say to use potassium carbonate to develop it, but I'm set up for sodium carbonate. I emailed them asking if sodium carbonate would work, but haven't heard back from them.
