BIN under SW white lacquer2/27
I called Sherwin Williams chemical coatings and the guy told me he didn't know because he doesn't have any test or proof to tell me either way.
If you are looking for problems down the road use the BIN.
I'd go and get some appropriate primer and make sure I didn't get a call back on that job.
What are you going to save? $60?
Thanks for the response Leo. Thats exactly what I'm going to do.
Using laquer over BIN is a really bad idea. Dried BIN can be wiped off of surfaces with denatured alcohol or acetone. They are both aggressive on shellac products. Alcohol is the shellac solvent.
Laquer thinner is the solvent for laquer.
Laquer thinner is a different mix of solvents depending on the brand. Regardless of the brand the major constituent is acetone.
Laquer will try to chew into the BIN primer. It will cause wrinkles or failures in the topcoat.
When it comes to finishing never take short cuts or skimp on material , you’ll always be glad in the long run. Believe me we’ve made all the mistakes now we do our finishing to the text book and never have problems. Knock on wood
