an update on this too. I essentially now have the hood blocked and how I like it. I blocked and blocked the skim coating until much of it was starting to sand away. Worked on some of the high spots, then went to the Slick Sand and let it do it's job. Suffice to say, the Slick Sand fill is amazing, blocks nice if you start with 120 first, and really helped to transition the hood from a disaster zone to a piece that now feels nice under the hand with all the guide coat sanded away. It's not 100% perfect, and I know you guys could probably get it better, but in the end it came out really nice. While getting the hood perfect was important to me, being able to actually drive this car in my lifetime was also important to me.
Now I need to get something wet on it so I can see how it looks with a shiny surface for the real test.
