Cosmic Shimmer Gilding Polish adds a lustrous metallic shine to many porous surfaces and is particularly well suited to paper chipboard wood cardstock etc. It?s water based and the colors can be combined to create custom blends that are unique to you and your project. Thin it with water to make a wash and use a fan brush to spatter. There is a sponge applicator built into the cover that can be used to apply the product to your surface. It?s recommended that you rinse the sponge before the first use.
