Sorry Irwin I can't answer your questions, but it did raise a few of my own.
You might look to see if the mfg'er has a website, if so they should be able

What is "Flex-I-Grit"?  I have never heard of it before.  Is it better then
plain old automotive wet/dry sandpaper?  Is it reusable or something?
