6 Cup Brush, Nylon Filament, 5/8-11 Thread, 2500 max.RPM

Good for sanding the back of pick ups for bedliner prep. The reason for four stars is the cups is s little hard to navigate opposed to the smaller 4 inch heads but the six inch head does cut faster.

Sanded the bed of my new truck with this product and I couldnt be happier. Conforms well to different textures and it did an outstanding job in scuffing up the surface to apply my spray in bed liner. I would highly recommend this product.

I used this for prepping my truck bed for a spray in liner. It doesnt take a whole lot of hand sanding to realize this things value - put it on a slow speed polisher and have at it. I got a 2 cup wheel to get in the tight areas that this larger one wouldnt go. Seemed to hold up very well too, I imagine i could do another 4 or 5 beds with this same cup, although I would rather take a beating as to do that (anyone that says this is easy is full of something) but sooo much less effort than hand sanding.

worked well on my truck

I started sanding my truck bed with sand paper, brushed wire, etc. It was taking forever. It took me 3 hours just to get a 3x3 area done. I know the pros must have a better method. I did a little research and this is what they use. You can do a whole truck bed in less than an hour with this thing. A regular side grinder turns way to fast for this. You need either a buffer type sander or a side grinder with a variable speed. Like 2000 rpm max. 1500 rpm is even better and more controllable. It doesnt take too much paint off, but it can if you stay in one area too long. It will take off loose paint and it scuffs rust enough to treat it with rust converter spray. Its the perfect tool for scuffing a truck bed. I dont know why these things arent a common thing to find. They should be sold right next to the bed liner paint in every store that sells the stuff. You still have to sand corners that the brush cant reach by hand but this is so much quicker and it really roughs up the bed for good adhesion. Prime the bare spots with a good etch primer or metal etch, clean the bed really good with a degreaser, ajax, purple power, dawn dish soap, then clean with the reccomended solvent, then apply your bed liner. I wouldnt use this for a thin paint because it leaves some deep scratches, but for a bed coating, it gives it lots of tooth for adhesion.

very aggressive very strong bristles.

This thing is awesome! First used it to scuff my truck bed before spraying in a liner. Since then I have used it for a lot of projects from cleaning aluminum to removing adhesive from a deck hatch. Tough enough to clean what you need but soft enough to not destroy what your working on. Very durable also.

Awesome!

I used a deck stripper and a power washer to remove the old finish. I was aggressive with the power washer trying to get as much as possible of the old finish. that left the surface fussed up. This brush removed the fuzz quickly without damaging the wood. much better than sanding. I used a 7 inch sander/polisher at 2000/3500 RPM. worked well at the higher speed but the brisells flared out about an inch. Wouldnt use it any faster than that. Deck is 8 x 40. There is plenty of life left in the brush

Worked great
