Like you, we are doing an entire kitchen. We are going to use a dark flat latex enamel basecoat and a lighter top coat. We are undecided about crackle finish as opposed to a wiped distressed look. I am pretty sure the crackle material painted on between coats can be purchased in gallon cans at Home Depot or Lowes. Jane syas HD has it in their Polo collection.
What are you going to use for a sealer/protector finish?
