Great product for flat surfaces, not so great for surfaces with too much contour! Being a rubber material you first think you can deform the block while sanding over contoured surfaces. You can as long as the curve is slight, if the contour is too great the PSA sandpaper will crease and develop an uneven sanding surface that can damage your finer surface finish(s). I have learned that for contour sanding you need a block you can preset to the curve you want then place the PSA paper on the curved block.

One of these blocks was introduced to me my interest in auto body work was rejuvenated. After buying a couple rolls of different grit sandpaper for the block I was astounded by how well the paper sticks to it and how easy it is to change the sandpaper. I blocked out a big patch of Bondo in no time with little effort. This tool is a must have for any type of sanding in my opinion. The block did accumulate dust by after a simple blow off with the air hose it was ready to go again. On the block it claims it can be used for wet or dry sanding so the block can probably be washed. I did not attempt any wey sanding yet. One star reduction for being made in Taiwan.

Shipment was fast and item was received early. I like the Dura Blocks because they provide a flat surface from a limited amount of effort. Also because they are very light to handle, yet feel solid and true. The size and shape is also very user friendly. I have two 11 inch and two 16 inch, so I can keep 80 and 180 on each pair and thereby dont have to change paper if the area I am working needs the shorter or longer block. I highly recommend Dura Block.

Excellent fairing block! Have only used it a little bit, but works great so far. Really nice combination of stiffness and flexibility.

A great sanding block; It is lightweight and stiff, still with a bit of flexibility. "Tis perfect for massaging those long panels to create that flawless bed for the perfect finish.
