My 1990's barn had the original stain on poplar wood. I used the stripper with the Butyl Boost. This combination stripped the stain right off and I immediately applied the Neutralizer and Brightener. My barn looked brand new. I recommend these products to anyone. I'm very happy with the results and would gladly post pictures if that is possible. All of the customer service folks are awesome. I called, they answered, I ask questions and had conversations with people with experience. I appreciate their recommendations and advice because this is the first time I've attempted a project of this size. My barn is 36x48 with a full loft making it a 2 story barn. I've placed 4 orders and my shipment showed up in West Virginia in 3 days. Just like clockwork.
