Nobody likes sanding by hand, and to make matters worse, cutting paper to size and mounting it is usually a PITA, too.  This generic sanding pad from Auto Body Tool Mart at least simplifies prep part of sanding a bit.  It accepts 6” round dual action (DA) sanding discs without any mods, and the discs attach via the same method as the power sanders: a hook and loop fastening system.

You can buy hook and loop backed sanding discs in bulk from any number of sources online, and in any grit you need.  The block itself streets for only $14. 

Now if they just offered a way to get the same level of detail without having to do the work by hand, I could really rejoice.  But any little bit helps.

    What are the different grits available in 6″ hook and loop? I’ve only seen the real fine color-sanding grits (1500 and up) available in sheets. Can you even wet sand with hook and loop backed paper? I use the hand sanding blocks for wet sanding. Granted, sanding down the skim coat of Bondo uses grittier paper in which case this would probably work pretty good.

  2. Evan,
    Not sure if I’m misunderstanding your question, but 6″ hook and loop sanding discs are available in any grit you can think of, much like any other abrasive product. I’ve seen it in 80, 220, etc. Was there something unique in the hook and loop that you were looking for?

    Here’s a bit of a selection from a quick amazon search:

  3. Rick,

    I think Evan is asking where he could find 1200, 1500, 2000, or similar superfine grits for this block. Although I too have had difficulty sourcing these grits in anything other than sheet form, I think McMaster has something compatible.

    Head over to http://www.mcmaster.com, and search for item # 4321A35. These are plastic-backed discs, so the cost is higher. Also, although the package size is 50 discs, you can order a fraction of a package, albeit at a 20% penalty charge.

  4. I must mention that the discs I mentioned in my previous comment, and the sanding block described in the above post may be incompatible with each other. The discs, being plastic-backed, might not be flexible enough to be securely bent and fastened to the sides of the block.

    Festool carries 6″ H&L up to S4000, althought it does have holes. The finer grits are often used for solid surface work.

  6. Jim,

    I’ve been digging around but cannot seem to find out what S4000 refers to. If it’s a FEPA grit standard, then it’s approximately 1500 grit, but then again it would then be designated P4000 as opposed to S4000. Maybe it’s a Japanese standard grit, but then again why would a German company be using JIS standards?

    Almost all searches for “S4000 abrasive” results in a Festool product mention.

    See: http://www.festoolusa.com/Web_files/Grit_Comparision.pdf (but doesn’t map Festool’s 4000)

    See: http://www.festoolusa.com/Web_files/Abrasives_brochure.pdf

    The ‘S’ I believe is Festool’s designation for silicon carbide. See page #3 in the above link for their range of both silicon carbide and aluminum oxide abrasives.

    Also, take note of the foam fiber backing for the S4000. Call them and request a sample.

    Hope this helps……Jim

  8. Ah, ok, it makes sense now. So S4000 is a silicon carbide P4000 grit abrasive.

    This grit size is not on Festool’s chart probably since grits finer than P2500 are not standardized and the micron size can vary based on the manufacturer.

    The easiest solution I can think of is to use this block for grits up to P4000/1500 grit, and a traditional sanding block for 2000 grit if it’s necessary.
