The surfaces are blurry because the silicone surfaces that touch the resin arent as smooth as they look. There are two fixes to this:
1. You can coat your surfaces with a thin layer of resin after you pop them out of the mold. You will have to prop them up on toothpicks (or something similar) to allow the excess resin to drip off.
2. You can use the Castin Craft gloss sealer spray to apply a thin coat to the finished casting. This will give it a nice shine.
With either method, you may need to lightly sand with a very fine grit sandpaper (1500 to 2000) before applying the resin or gloss to get make it appear as bright and shiny as possible. Make sure your sandpaper and/or casting is wet and wear a particle mask to avoid inhaling resin dust.
