I am out of Mold Star 16 and need to finish side two of a mold before this weekend - getting something locally is not an option (can't find anything in Hawaii) and can't ship it in time/budget.
I have enough to coat the MDF master, and then I was thinking I could back the rest with clay and seal the box on that side? Is this feasible, or is there a better option? I also have a few chunks and scrapings of silicon that I can use as filler but not nearly enough to make a solid wall. I do not have enough MS16 to coat the master, lay a filler, then coat the filler.
Thanks for your help, this is my first full-size attempt at a mold.
