MJ is right. West is a good product, however West's price is without a doubt the highest by far. West's tech support is excellent and when you are dealing with expensive chemicals and you are not a chemist, support is important. I use Raka, (raka.com) which is less than half the price of West and if you have a question and you call Raka, your question will probably be answered by Larry, the president of Raka. Alot of guys who are into building cedar strip kayak's and canoes prefer Raka because it doesn't blush and is much clearer than other epoxies. (Seeing the beautiful wood is important to them!!) I have also used US Composites and they are cheaper yet. Don't know about their tech support. Never needed to use it. Unless you live in Florida, you need to buy Raka or US Composites online. One thing to keep in mind, epoxy resin and hardener have an extremely long shelf life. (Over 10 yrs) Even after 10 years, the resin gets a darker color but still works fine so buying by the gallon makes sence. US Composites has an offbeat URL and I can't think of it off the top of my head, so I will post it on Tue or Wed. I hope this helps!!
