Lately, I've seen sandpaper grits with a P in front of them. I used to just get, say, 400 grit. Now, there is P400. Are they the same? I looked it up and Wikipedia had some chart comparing grits with a "P" and ones without. It stated that one designation is US (without the "P") and the other is Euro/ISO (has a "P" in front).
It seems that all the sandpaper I've seen has a P in front of it. Did we switch over? Even stuff sold as "400 grit" says P400. They are not the same, according to the chart; P400 is closer to 320. I'm wet-sanding my car and I'm using what I think is 800, but it has "P800" on the back. P800 is similar to 400. Anybody got any insight? |
