I am working on a piece and want to layer stain to give depth and dimension. I plan to use a mustard color deep stain, MinWax chestnut and then finish with a product called antique door toner. I believe all products are oil based. Can anyone give me tips on how to do this as I would like to have all stains show through and look blended. I know I need a sealer between coats too. Can someone be specific in what brand and kind of sealer I should use? Thanks for your help!
