Is it possible to apply spar urethane over stain?

Member who is well-known. You may apply a spar urethane over water-based stains as long as the stain is totally dry before proceeding. Spar will stick to the fibres of the wood as well as the pores of the wood, sealing and protecting them. Because water-based or oil-based dyes do not fully seal the wood, the spar will be quite acceptable.
