        West System epoxy is really great to use. I use it in general applications for marine repairs and for boatbuilding. West works very well.

            I use the 206 hardener in conjunction with the epoxy 105 for a great many projects on my old Morgan O/I sailboat that I am in the process of refurbishing.

            The service at our tiny store in Vero Beach is always great and very helpful with the DIY tips.

              Comments about #206 Slow Hardener:

              I increased the hardener/resin ratio (more hardener) when working below 60 degrees ambient. It usually took overnight for my repair to completely cure. I've had very good success with this product.

              Service and delivery comments:

              Product was bought at a West Marine store.

                    I used West System 206/105/422 to seal my bottom after taking it down to clean fiberglass. The removal of material left low spots which I added colloidal to the mix for and it faired beautifully and hard as a rock.

                          Great stuff. Extremely predictable curing rate. Brush or roll a coat on lightly sanded wood, allow to cure overnight, and, the surface is ready for paint or a second coat if desired.

                            206 allows me time to get everything clamped up perfectly and also allows me time when the temperatures get a bit warmer in our hot Texas summer. Using the pumps takes all the guess work out of making a perfect mix every time.
