P tex boy, do it by your own, not hard at all, just warm up the bases with an iron or a lighter, after a few minutes you are good to go, light the ptex, let it burn til its dripping... wait some time and warm the bases again drop some more ptex if you want, let it cold for some time and then with your metal scrapper, scrap out the remaining ptex. Now you are good to go, thats how I do it and it works perfectly, people probably do it all different.
