Mike:

Another hint that I can give you when working with large areas of plywood 
with West is that you want the wood warmer than the resin to avoid bubbles 
and pinholes in your surface.   If the resin is warmer than the wood it will 
cause the air in the grain of the wood to expand and bubble to the surface of 
the resin resulting in little pinholes that might result in more labor 
sanding and filling.....possibly resulting in a less than perfect speedy 
Tailwind......can't have that!....I use heat lamps to warm the wood before I 
apply the resin.  It doesn't take very much heat, just warmer than the resin 
which should be at "room temp".  Rolling the resin on works well but just 
pouring a blob on from a cup and working it out with a soft squeegee such as 
used for Bondo works much faster and results in less air entrapment if your 
laying your glass cloth.....After you have the surface coated and are having 
your congratulatory coffee or beer check the surface for bubbles and very 
gently brush them to reduce your finish work later for at least the next 
hour........Let the resin set up if over cloth and then apply another coat of 
resin before it is completely cured..... this will fill the weave entirely 
resulting in less filling and take care of any amine blush bonding 
problems....Don't worry about putting it on heavy, you can sand and fair it 
easily.....like I said earlier the West sands easily but make sure to remove 
the "blush residue" which is "waxy" with some warm water and ammonia before 
sanding.... then your sanding will be trouble free and fast....

You said you bought 206 Hardener instead of the 205 which is great for laying 
the glass but you probably don't need the extra time for any other type of 
work unless your in a above 80 deg F shop environment.
