You use the tip to melt the P-tex strip holding it while the flat P-tex strip in on or just above the base, and then to spread it into the gouge. You have to be careful with no temperature control because it could burn the base, but if you ever used a soldering iron it is easy to figure out. I just hover it just above the base--or barely toughing it-- and the P-Tex melts like wax. Look, I got this for cheap on an ebay auction. Previous to this I just burned a candle or used powder and that worked fine. You will probably have to go over that repair more than once with a candle, since you may need more P-Tex after it hardens (it might shrink a tad in spots when cooling), but that is no big deal assuming you have a sharp scraper. Whether you want to go to the trouble of restructuring the repair is up to you (there are lots of videos on this type of repair).
The good news is that this is an easy repair and difficult to screw up if just using a candle. For example, if for any reason the P-tex doesn't hold next to the edge, only a small part will start to come out. So then you can find some Metal Grip and repair it again (unless you already got some...then just use it). I just mentioned the KUU tool because it works great and, based upon where you ski, you could buy one and keep your friends and family skis repaired with little effort for the next few decades.
Oh yeah, burning P-tex smells. Have adequate ventilation if doing this in your house or use your garage. You can warm your skis in the house before starting the repair.
