HomeRight C800418 Stain Stick

I bought this a few years ago after experiencing a tragedy trying to stain my 30 foot deck with a sprayer -- what a mess! The stain stick cut the time down by more than a half, works like a charm and is easy to use. When I went to use it a couple of years later, I needed a replacement head and returned to Lowes but they no longer sold the product. Cant' find it anywhere. What a shame.
