So resin is very forgiving in terms of how it will fill in scratches over previous laminations and sanding coats. Sand paper scratches in wood isn't that way. Those need to be found and dealt with in grades of elevating grades to bring out the best in the wood, so the resin can do a better job praising the grain. Also I learned from my friend Ian to let your Nant do the looking when it comes to imperfections in your works surfaces. The eyes are too close to the lazy brain that just wants to surf the darn thing. The hands can find what needs to be sanded down.
