Thank you Charles. I also sent an email to your website asking the same question but also posted here because I wasn't sure I would get a reply before I had to deliver the Pine discs. You can disregard that email.
Carloz, I've known this customer for 30 years. The offer to do the complete job for him was made and he chose not to have me do that. It's his daughters wedding and he wants to do the staining with her. A Father/Daughter thing. It's probably a $$ issue as well. Weddings aren't cheap these days so you cut corners where you can. I'm putting the blotch control on because I know they would just put stain on raw Pine and call it good. If they mess it up, they won't come back on me. What I would likely hear is "We should have let you do it".
