West System Products are wonderful for both hobbyists and professionals. Convent package sizes make it easy to buy the right amount without waste. 205-B is great for cold weather or fast cure needs.

Timely delivery of product is always desirable. West systems offers among the best performance for an adhesive and structural epoxy. Not to be confused with a slow cure or high depth of pour product.

Can't go wrong with West System. This is the fast hardener, compared to the Slow. Duh. The other pic is of their 404 high-density filler. I use it to make the epoxy thicker. I have dyed it also to make it match the color of wood. Works great! Thanks West System, your a good guy.
