With urethane, it is possible to get a very good repair. I don't think nitro repair is mindless -- it takes skill too and as mentioned, you can have more shrinkage with new material and may need a quick level and buff if the repair becomes visible again. But I don't think anyone can debate that nitro has the potential for the best repair work if done correctly. With urethane, you want to sand the area a bit and then add the CA glue -- then level and buff carefully. It can be a very good repair but I think I could probably notice any repair work done with urethane -- fortunately, most customers and players won't be able to notice it.

I prefer urethane but the finish must be very thin -- and I think it is much harder to do a thin urethane than it is to do a thin nitro finish. So nitro is definitely superior in that regard.

As always, take proper safety precautions with any of these finish materials !!!

I sometimes sand through the lacquer, especially at edges.
I bought Mohawk pre-catalyzed lacquer in a rattle can for touch ups.
I cut a slit in a pice of paper, hold it above the sand through spot and spray a few coats on.
This stuff is dry enough to polish in one day and looks great.
Just wanted to pass this on.

Another way to minimize "sand through" on the edges is to "band in" the edges and then spray the rest of the surface. This puts a little more material on the edges. Also when using a ROS to level sand I stay off the outer inch of the surface and level sand that by hand with a sanding block. The little bit of extra time hand sanding saves the aggravation of touching up the edges.
