Dura-BlockAF4400 Black Standard Sanding Block

Perfect block for body lines

This is a great sanding block. Perfect for those narrow areas where the normal width sanding block won't fit! Nice flat sanding! A must have for anyone who sands body filler or spackle ect. Recommended for sure!

I am by no means a proffesional when it comes to body work and paint. I have been able to get almost professional results though. (apply paint, sand off, apply again until its good)When I used body filler I was getting low and high spots that were so subtle I couldn't detect them in primer and sometimes not even in the base coat. It wasn't until I applied clear that I saw them and sometimes not even right away.I discovered the term "block it out" and found out that my small sanding block and fine grit paper wasn't adequate. I bought the adhesive roll of sand paper in 80 grit. It turns out that really low grit (course) paper does a way better job of making a flat surface. Starting with fine grit will just keep the contour of the repair. They use this up and down/right and left and at diagonal angles as well. Keep the block in the same orientation and do the red lines on the British flag.In ASCII do the following patterns: / \ | -- Remember to keep the block in the same orientation. With this long and skinny block you are pulling and pushing the long edge at times. Then gradually lower the grit and continue using the block. Some people use a 'guide coat' of some type of spray paint that doesn't match the color of your body filler. When you sand it off you should see paint in the groves. (that way you know you still have sanding marks to get out) You should fully sand off the guide coat once you have it flat and smooth. Don't sand the surface finer than 600 grit. (you want maximum adhesion and primer/paint can easily fill in 600 grit sanding marks.It is hard rubber and doesn't give. You can probably find something flat to use instead but this works great if you are willing to spend a few bucks. The rolls of adhesive paper aren't terribly expensive when you consider that all sand paper is pretty expensive. (except those dollar store foam sanding blocks which work great on prep work and are grit - unknown) I did pick up sanding dust with my block before using the adhesive paper since it is so sticky it would be hard to get off otherwise.I watched a ton of videos and this brand seems to be popular with the group that knows what they are doing. I probably should have ordered the entire kit with several sizes and shapes of block. That seems like it is cheaper in the long run if you use the other sizes eventually.

Good product.

This sanding block is the perfect tool for block sanding both wet and dry the curved indentations on older VW hoods . It's perfect size makes it easy to maneuver without overlapping the raised edges and does extremely well within those confines . Inner parts of my hoods now coming out looking really smooth and straight .Should have gotten this block a long time ago !

For such a seemingly simple thing, an 11” length of rectangular rubber, this sanding block made all the difference when blocking my new quarter panels. The contours were so much easier to achieve with this block and using 80 grit PSA sandpaper to knock down & shape the high points, and then feather edge using 150 grit. The block is easy to grip using nitrile gloves and it has just the right amount of stiffness for panel contours. The passenger side I did not use this block and it took me more than twice as long, this block made the driver’s side much easier. I’m not a pro, I’m welding in new patch panels and doing my own bodywork to save some $$$ prior to a paint respray by a pro, but this save me a lot of time and made for professional-looking results.

I assumed I was getting the 'standard' size, which I assumed was wider. This block is super narrow and useless for my fabrication purposes. This block may be useless for details, but not larger areas. Y'all, please read the dimensions. It'll cost half the price to return this, might as well keep it. :/

Straight and true, it's just what you need to sand down a nut.
