Smooth-on Class Question

I haven’t but I’ll say this from what videos they have on line. It’s good as it will give you information on how and what products are good for your project.
Once you learn these you can or should be able to figure out how to cast anything in the right silicone, mold etc.
In taxidermy there’s a good use of tin silicone cause it’s either being casted on moisture surfaces or looking to get a few pulls with out it breaking down then once casted and you plan on making more casts from that cast you would then use platinum silicone as that longevity lasts longer than tin silicone.
Let’s say this. I made a mold of a bear nose. From there it was molded in tin silicone, cast was pulled and any repairs were made to the nose. Well if I made a mold in tin silicone again that mold would last 6-9 before it would tear apart but I could made a bunch of them right now. If i needed to recast it a yr from now it would fall apart where as if I did it in platinum two yrs from now I would still be able to use it.
Plus the year strength between the two is way different.
So it might be good to go but it’s up to you
