: Worry about the runs early -- and remove them as best you can with a brush or
: squeegee while they are still liquid. Otherwise, try to remove them with a
: cabinet scraper the next day -- after the resin sets, but is still soft,
: or "green". It will be too soft to easily sand at this stage.

: If you are using 6 ounce cloth or a cloth which has a deep or coarse weave it
: will take a few more coats to kill the weave than if you are using 3 or 4
: ounce cloth. That is normal.

: There is also an effect called "telegraphing" which you may be
: experiencing. The newly applied resin is following the curves of the
: previous layers, and not simply leveling out by flowing into the shallow
: hollows. In this case you have a nice thick layer of plastic building up
: and covering your glass fabric, but even with 5 or 6 coats, you still have
: a textured surface. This situation is simply solved by a light sanding.
: You want to knock off the high spots of resin without sanding so deeply
: that you actually get down to the cloth itself. A gentle touch and medium
: to fine grit sandpaper should do. You can do this with just a sanding
: block if you wish. Power sanding is faster, but not necessary. If you have
: two fill coats on and the resin has hardened enough to sand, you might
: sand it lightly before putting on a very thin coat.

: Or, if you can sand it smooth without hitting any glass cloth, then you are
: done.Go straight to the varnishing.

: hope this helps

Thanks Paul- I am using 6oz glass. I will apply one more coat and see if I can get the coating to a level I feel comfortable to sand back a little.
