wellll, I wouldn't want you to toss the Hysol away that comes in the kit but....
I bought the gun and the mixing tips, many of them. I bought pre-filled double barrel syringes of Hysol also available from the same outfit. It will cost you plenty if you hope to do the whole job that way. I was not aware of the empty barrel syringes but I would certainly give that a try with the product that comes in the kit. I bet it is no fun to try to get the product into the syringe though. Don't bother trying to mix up Hysol and stuff it into a syringe. It will begin setting up quickly and it becomes very difficult to push the plunger. The gun and syringe set up is one thing I will always recommend. The nice thing is, you only waste the product that is inside the mixing tip.
