@Brad Hays .....
I'm using mostly Finkat papers from Japan, and I can't say that it clogs up less than other papers.....but, I can say that I'm very happy with the results I'm getting with it.
There are a couple of points to consider, that will help to reduce the clogging.....
Sandpaper can be used with too much pressure. This causes more heat than less pressure. If excessive heat is a problem resulting in clogging, then you might want to consider that you're sanding with the wrong grit.....and, a coarser grit should be used.
Some woods, especially those with a high oily content, will clog up sandpaper much more easily than others. Bocote is one that comes to mind, off hand.
It's easy to over-use sandpaper, and many times, the solution is to toss it......and, get a fresh piece! Bite the bullet, and get used to the thought of spending a few more bucks for sandpaper.
I use a metal file cleaner to clear the clog. Helps.
I have used the rubber abrasive belt cleaning sticks on sanding discs, whereas it works fairly well.......but I've not found it very useful for sheet sandpaper. I've never tried a file card for this purpose, and when the opportunity to use it for cleaning up some sheet sandpaper strips comes up, I'll give that a try. Thanks.
