I came across this old beat  up dresser which had great elongated mirrors on the side. I removed the mirrors and did away with the dresser!  I must admint that the mirrors sat around for awhile until it came to me - I was turning these old mirrors into a horizontal mirror with new antiqued hooks.  After investigating the wood, I realized that it had been stained with a black stain.  Since stain does bleed through I knew I needed to seal in the wood from bleeding through my final finish.  I grabbed a can of Zinsser BIN Primer - covered the mirror with tape and newspaper and simply sprayed away.  Zinsser BIN sealed in the old stain and avoided any type of knot bleeding.  I love the spray can - no fuss or mess nececssary.   The recoat time is fabulous as well - 45 quick minutes!  I next sprayed two light coats of Rust-Oleum's Satin in Shell White Satin.  The satin finish was perfect for that antiquefaux  finish!  I pre-drilled holes for the two antique bow hooks I found at a local craft store.   From almost trash to terrific with a couple of cans of spray paint!
