First grab your safety gear. Clear Casting Plastic is a two part Epoxy resin. Mix the resin, scrape the sides of the lids to get all of the resin. To prevent bubbles gently but thoroughly mix the two parts together. Clear casting plastic has a 45 minute pot life so that gives you enough time to mix and degas the mixture if you have the capability. Clear casting plastic is recommended for this project but other resins will work as well. Clear casting plastic has the perfect viscosity or thickness because it is not to thin that it will seep out of the cuts but it is thin enough that it can be forced into the mold using a syringe. Once all the molds are filled wait 14-24 hours before De Molding, at this time the plastic parts will be flexible and because they are flexible it will be easy to trim the pieces if they need to be trimmed. Once you are finished trimming wait another 24 hours or heat the parts at 200-250 degrees F for 1 hour and they will become solid. Once the pieces are solid you can paint them. The easiest method is to spray paint the peices with white paint then paint on a white primer followed by two more layers of any color water based or oil paint.

    To any first time buyers mix slowly you have plenty of time before it starts to thicken. The first time I tried clear casting plastic I mixed it like a mad man creating a bubbly cast. Just mix slow and its crystal clear.
