Get hull surface even?

[PAR]

1708 is lightly stitched with common thread (polyester I think). With the mat down, which is correct for good inter-laminate bonds, you should lightly kiss the surface with a DA or orbital sander, which will remove most of the threads and flatten the surface. It'll still have undulations, but it will be much better. If it's still got a lot of divots, a light skim coat of fairing compound, before a finishing cloth will do. Conversely you can use mat, which is wasteful of resin and heavy, but effective in a non-weight sensitive area, especially high traffic locations.

Thank you very much for the help!

As PAR said, CSM can be used on the surface if weight isn't much of an issue. The CSM also helps because it creates a durable protective layer to prevent the structural fibers from being compromised by being sanded through, and this happens all too frequently when trying to get the surface looking good.
