: 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

I agree. My extra 2 cents.

If you apply the seal coat at night to avoid the outgassing bubble problem, the next day the epoxy is set enough to scrape. The fuzz is easy to knock down while the epoxy is still green with a cabinet scraper. It takes only 10 minutes of scraping. You should apply the glass and epoxy the evening following the seal coat to to get the cross-link bonds between the epoxy coats (and still take advantage of the falling temperatures to avoid any chance of out gassing bubbles). The fuzz dosen't hurt anything if left on I just find it easier to smooth the wrinkles out of glass cloth after knocking the fuzz off. By using epoxy that doesn't blush and by only waiting 24 hours between coats I don't feel the need to sand.

If you don't have a cabinet scraper, buy one they are cheap, not even $10, and are without a doubt the best tool for removing epoxy runs in the fill coats.
