Smooth-on product, Rebound 25 question

Hey guys,

Trying to get some help from some sculpting pro's. I am working on a sculpture and I am using Chavant NSP soft -sulphur free clay. I'm trying to figure out how to smooth my clay out that won't react with the rebound 25 mold. I guess the proper term is that won't inhibit curing? I know to stay away from latex gloves and things that contain sulphur. I have also called the smooth-on company and they have said to test a small piece but I was hoping to get a faster result than testing it. Any recommendations would be great.

Thanks

Testing is always the best. But for smoothing NSP, you generally want to rake it with a range of coarsenesses (big teeth to small), and perhaps scrub with a bit of isopropyl alcohol at the end

NPS stands for Non_sulphur-plastilene I believe. If its similar to monster clay it should be fine

I smooth my sculpts with rough then fine sandpaper, the liquid agent being Citronella. Based on what I've read, there shouldn't be any curing problem.

Thank you for the reply, greatly appreciated
