Fast and convenient
This was my first time using West System epoxy. I bought this along with the kit with the 204A hardener. The 205 hardener worked great with plenty of working time for some butcher block waterfall counter tops I was assembling. Thick enough to address some minor gaping issues yet thin enough to squeeze out properly for a great wood joint. I've use the hardware store epoxies or small bottle epoxies for many years and finally bit the bullet for West System. More expensive upfront but much cheaper overall. It is so much more convenient. The pumps are quick and so much more accurate for ensuring a proper cure. I highly recommend this product.

Works as advertised
West system products worked very well. Easy to mix and apply with use of measuring hand pump, and syringe. Used to harden soft spots on RV floor. Make sure your holes are NOT drilled completely through the floor, or product will just run through. This product has a thin viscosity in order to inject where needed. Takes time to harden. Starts to harden within about 10-15 minutes. Oder is minimal which was a great surprise. Still used in well ventilated area.

West System 205-A Fast Hardener
The West System is by far the best epoxy on the market to date! Easy to use! No mass. Simple to mix by pump! Use 205-A (Fast Hardener) or (206 Slow Hardener) I have been using it for 25 years and never had a problem with it! Great Epoxy!
