reranch sanding question

[GOG427]

from reranch its how to sand sealer but doesn't say dry or wet or what grain of sand paper any ideas?

"next apply a high solid content sand and sealer product. Parks Corporation makes a nitrocellulose product which fills this requirement nicely. The application is simple as the sealer can be brushed on. Brush on the first coat and allow to dry for a few minutes. When the surface is flat (non reflective) a second coat can be brushed on. Allow this double coat to dry at least an hour (I usually wait overnight). When dry the coats can be block sanded flat. I suggest that this sanding be done in an area where dust is not a concern. You will see why when you begin sanding. I also suggest that you wear a mask. When this two coat application has been sanded flat (no shiny spots) wipe down with a dry cloth, inspect again for shiny spots and repeat."

I would go with dry and depending on how badly the surface is start out with either 320, 600 or 1000. That really depends on if you have bumps and valleys to flatten out or not.
