You have to rub in some of Excal's wax onto all the servings. I usually load up the serving with lots of wax and then heat it to make it soak in. I find that I have to lube less often if I do it my way than the recommened method. I use some softer string wax on the string itself. If you smell something burning when you shoot it means you should have lubed your serving. Hope this helps
