This all started a couple of years ago. What used to take 3 hook and loop delta orbital sanding disc ,now takes 5 of them.
I do the same sanding job on my little canoes just like I have for the last 20 years. I use the same company and the same brand of sand paper and grit. They just don't last anymore. I just don't get it.
Chime in all

I doubt that I do as much sanding as you do, LB, so it's been at least three years since I bought any sandpaper. Sheets that is. As of the ROS pads, they've never seemed to last very long.

Hey Ralph,

I think that I actually get better performance than I did years ago. But that may be because I now buy better (more expensive) sandpaper than before. I also have a better ROS than before, so it's difficult to judge. All considered, technology has improved the coated abrasives business, as with most things over the years.

My 2¢,
Tom

Pressing harder now in an attempt to work faster? That's certainly a factor. With high flex backing, a big factor, because you bend so much you break the resin and kick grit. I thought I was running into the same problems until I realized that I was starting one grit finer than usual and trying to force things. Back to starting coarser did it for me. Klingspor is what I'm using.

In my experience paying a little more for a higher grade sandpaper makes a noticeable difference in lasting longer.
