Bee Natural RTC Sheridan Resist & Finish is a superior, easy to use finish for all top grain leather. RTC gives superior resistance and top gloss for maximum contrast when antiquing or staining leather. This is a safe non-toxic, non-hazardous, odor-free, gloss finish that doesn't peel or crack. It can be used over antiques, dyes and acrylics and allows you to oil over it so the leather still breaths. This one product can be used as both a resist and top coat when antiquing leather.
