I use the gun slick. You can watch the foam turn into a blue liquid from the copper fowling being removed. The big key is to make sure you get ALL the remainder of the foam out of the action. If not and left in there it turns to a hard sticky gum. I litteraly glued my action shut years ago from not cleaning out the excess foam left in the action.
