I bought this brush to upgrade from the big-box $5 brushes whose bristles collapse after a few months. I use it on the fully-lined fender wells of my Honda Ridgeline and my wife's car too. The length is great and it's easy to grip. The problem is, the bristles are too stiff to work into the uneven, concave surfaces in my fender wells, particularly on the truck. I always have to go back over them with some APC and a blown-out microfiber towel to make sure I get all the crevices. I feel like I'm in a "Goldilocks" situation -- I have the too-stiff and have had the too-soft; now I need to find the just-right. If Adams made this brush with the bristles from the wheel brush, I think it would be a big improvement. One more thing, too -- if the handle had a 15-degree reverse curve, it would enable me to get the brush around the tires and more easily get to fender well sections behind the tires. If your fender wells are completely smooth without uneven surfaces, or you're using it as a tire brush or to clean floor mats, it's fine. I am not recommending it only because it does not work well for the purpose I bought it for.
