Good idea to include the other discussion.
Have you done resin casting before?
Be very careful. Make sure you're using gloves and mask, in a well ventilated area.
My understanding is that this sort of resin is one of those compounds that exposure over time causes increased chances of allergic reactions.
I have not cast with Resin before. However I do have a friend who has and he's agree to show me how to do it (and I'm a little familiar with the process thanks to the internet as well).
Naturally I plan on doing it in a well ventilated area as I like my lungs, but with winter coming up I'll have to work around the weather as well.
So all-in-all definitely a challenge I'm willing to accept as it will still be cheaper than trying to kit bash all those Gauss Blasters, Flayers, and Tesla weapons.
