Sez who?

Light sanding, done by hand, with a sheet of medium to fine grit sandpaper simply wrapped around a block of wood, will knock down the fuzz without sanding through the layer of resin that resides on the surface of the wood.

A scraper -- can also do the job. There are two types of scrapers to choose from: the common paint scrapers and the relatively less common cabinet scrapers. These are sharpened in different ways and cut differently but for just knocking down some "fuzz" either will help. Again, go with a light hand.

While the resin is fresh and soft you can easily smooth it down with any of these methods.

Don't try to do a complete sanding job. Just knock off the sharp or rough edges.

Why do you want to do this? Simple. There is a good chance that "Fuzz" can catch the fibers of your glass cloth as you apply it, and make it dificult to smooth it out.

As long as you don't go completely through that coating -- and it is a relatively thick coating -- you won't touch the wood itself, so you won't have any problems with "blotchy" coloring. Any scratch marks made in the resin by the sandpaper or scrapers are filled in with the next coat, so they don't show, either.

hope this helps
