I've been looking for a lower grit, flexible, durable sandpaper to help me sand small things, or anything with tight corners. I found some videos where someone was using a 3M sandpaper that seemed to work a lot like Zona paper, very flexible...but they had 150, 220, 320 grits (coarser than Zona goes, or for that matter 3M Tri-M-Ite).
I eventually discovered that they were using "3M Sand Blaster Pro Ultra Flexible Sandpaper" which as far as I can tell, has been discontinued. The sad thing is, this is exactly what I was looking for. It had some kind of silicon backing, was not just ultra flexible, but it was tear and puncture resistant, and effectively rebounded back to its original shape. So you could contort it to get into any corner or slot, without creating any grooves in said corner or slot, and it would sand perfectly.
I've searched and searched, and only found 100 grit available mostly on eBay or Amazon (suspect its from people's old stashes), which is too coarse for my tastes and needs.
So I'm wondering if anyone knows of anything similar, that might work in place of this stuff. I was particularly interested in 220 and 320 grits, but I can't find any of that in the 3M ultra flexible stuff anywhere.
