AF4400 Black Standard Sanding Block

Solid block

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.

This worked very effective on entire vehicle. It is easy to use and can flex so that it can take curves as well as straights. I even used it to get that "hard to get" line on the vehicle door. It word very good. You can even get the larger one for longer straights like for the entire door but if you have a budget get this one as it can work anywhere on the car. I'm sure a longer Durablock can have a slight flex as well but this one did a fantastic job. I will also be ordering the longer one.

I need the big one not this slim ot

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!

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

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.

It's a little thin and little for my hand to hold it I don't use it much for that reason

Very small and price not worth.

A lot smaller than the pictures protray .

El producto trabaja muy bien y es de muy buena calidad solo tomen en cuenta que de lo ancho es más pequeño. para tener una referencia es como la mitad de el ancho de una tira cubitron de 3M y de lo largo tiene lo de 4 cuadros de la tira cubitron de 3M

Great product works well

really liked it, has helped me a lot, only thing was i didn't read the size, and is smaller than i thought it was, however it turned out just fine for the car i am sanding. the picture looks deceiving according to size
