Hi there Lumber Jocks,
This Lumber Jane has used poly-shades many times with good results. I agree with others that the product is best for small projects and for the home DIY'er although I have had many contractors specifically ask me to use poly-shades on certain projects like doors for example. I apply it to small projects and I try to place the surface to be stained horizontally (if possible) using a natural bristle brush. I take doors off the hinges and lay them on sawhorses. Depending on the shade I'm using, I apply multiple coats as per the directions of applying, letting dry, lightly sanding and re-applying. Once I have achieved the depth of color I want, I apply one final coat but this coat is applied with many long brush strokes back and forth. Even after I am done applying the final coat, I keep brushing long strokes from end to end with the same brush. This step causes the finish to polish-up to a nice shine as if you gave it a final poly only coat at the end but really you are just polishing with just the poly-shade product. The more you dry-brush, the shinier the final outcome. The long strokes prevents brush marks but if the object is too long for you to maintain long brush strokes, just lift the brush gently and slowly as you are moving it across the surface until it's completely off the surface and start again about 6 inches behind (overlap) from where you left off at by moving the brush as you set it back on the surface. It's a great way to save time for me and as I said, sometimes I am actually required to use the product.
