I ordered a new piston and examined it closer to find some very small scratches. Im wondering if these small scratches are a big deal and I should get a new piston, or is this fine to go in my engine? Thanks.

I use old 300 wet dry sandpaper under hot water, and lightly sand round and round under the water. I sand all the edges that touch the cylinder except the ring grooves. I also clean all the edges inside the cylinder.
