Great prices and the stuff is very flexible. You can work with it alot better than the stuff they have at the shops locally. You also get enough of it (cheap too) that you can mess up during the learning stages and it doesn' t cost you so dearly. You may find tricks to working it. A hair dryer and hot water (doesn' t have to be boiling) will be a few methods to try. It should start to do what you want it to around 175-200 deg. F if I am not mistaken.
I have purchased and used the .02 green from them with alot of sucess. Good luck! The section you' d want to go to will be here:
