Wow, I can't believe I missed this thread. This product sounds like a miracle.

I am a big fan of matte finishes lately because they hide many sins of use.

I would be very curious to see how this product performs on wood sanded to 150 vs 220 vs 400 vs (as you and I like to do) 600 or 1000... I think we have both found that while high grit sanding is discouraged for other finishes as well, it has never adversely affected the finish for me.
