west system sucks to be real honest for fiberglassing you need just fiberglass resin that uses peroxide hardner. I just bought 4 gallons from Parker Boats works for 21.50 a gallon with hardner. it's a 10:1 mix on there stuff. you need to first dry fit your cloth to where you are going to glass it in and cut it with sissors to fit then lay it on a piece of old scrap wood if it's a big piece of glass and pour the resin on the glass and get the glass soaked solid wet with resin then wet the whole area you are going to glass with resin. then lay the glass in place it will stick and fit correctly since you have it precut. best to get a cheap glass roller to roll out the air bubbles and smooth out the glass good. see the area i put in yesterday for glassing 101.
Make sure you grind both pieces you are glassing even the fresh wood so the glass has an area to grip for strength.

Rollers are really a need to get the glass layed out smooth and airless.
