Blocking

Here's my first, quick pass of blocking the top portion of the driver's side fender. Hard to tell in the picture, but it looks pretty good. Only a couple of very small low spots, and the high spots barely got into the thin layer of glazing compound.

If you look carefully, you can see the Xs formed by the sanding pattern. That will disappear at higher sandpaper grits.

This is tedious stuff, but it needs to be perfect--we've all seen those freshly painted cars with the little waves in the paint when you glance down the side.  Effort here will go a long ways to preventing that bad effect.
