Is the Amazing Casting Resin cured piece UV stable?
No. The Amazing Casting Resin is opaque White and will yellow slightly over time if it is exposed to UV light. Clear acrylics or lacquers work well for protecting the resins from changing color. There are two ways of applying paint to achieve the best adhesion. First paint the mold and allow it to completely dry before casting your resin. As the resin flows into the painted mold, it will chemically bond to the paint as the resin is curing and after the resin cures you will demold a perfectly painted part. Painting the mold prior to casting allows you to reproduce perfect detail by painting becoming the outside layer of the actual part rather than cover the exact cast replica with paint that could then cover up fine detail. The other option for painting your part is to paint the part as soon as you remove the cast part from the mold and after you remove any flash while the resin is still curing.
