Recommended by Reggie Ezell and Sheila Waters as an excellent gilding size. Create your design with Instacoll, let it dry for about 15 minutes, and apply your gold or silver leaf. Instacoll does not require a separate activator, but one can be used if you need to spend more time perfecting your project before laying down the leaf. Get a mirror gloss finish without agate burnishing on most nonporous smooth surfaces with patent leaf. The yellow color helps hide small imperfections in the gold leaf.
