I've read a good response here on conditioning and staining with blotchy woods. I have a stubborn pine that I stained twice. The blotchy side was embarrassing. I completely forgot to use my conditioner.
I've gone over it with both moderate to light sanding using 200 and 300 grit papers. Some areas show the original pine while others still have a light layer of stain.
I am using a water base stain and plan on going for another darker color.
Is it possible at this point to condition then stain before applying the final?
