Weathering Mix’ stain is alcohol based. The benefits of using alcohol are fast drying time which helps prevent ‘warping’ of the wood and it’s easy to dilute the mix to get varying degrees of a lighter stain – just purchase a bottle of 70% isopropyl alcohol at the drug store.
All are in 8 OZ. Bottles.
