Reinforcing With Smooth Cast

[Tikigod002]

So after building about 2/3 of the armor suit using the traditional pep / fiberglass / bondo method I grabbed some smoothcast 300 at an art supply store. I've been using a slush cast method on straight paper, without putting a layer of fiberglass resin on the outside first. Anyhow, so I have a lot of small droplets of plastic all over the place on the outside of my armor. Is there anything I can do to stop little drips running through the small gaps in the armor? Its a little messy, but I like how much better reinforced some of the smaller details are as well as the fact that since it dries so fast I can hold it in place to keep it from warping while it cures.

There are two big things you can do.

1) Use hot glue to plug up any (ANY) hole in the pep that's not supposed to be there. Tiny gaps the size of a pin needle can let out drips.



2) Resin the outside with FG resin. The casting resin saturates the paper after a while, which is why it can leak through. The FG resin acts as a sort of shield against that. Imagine pouring water on a napkin (This is using no FG resin). Now imagine having one side of the napkin covered in plastic wrap. There's a big difference.
