I'll give you a little advice here really quick. Depending on your tuning ability you may or may not want to tune the side and base edges. BUT, WAX THEM. Waxing a new pair of skis is like washing a new car. Maybe a bad analogy, but the skis will ove you for it. You can never wax a ski too much (unless you are using HF wax, but thats another story). Find out what the prefered edge bevels are, or if you have a personal preference, use those. For free ride skis i usually go 1 and 1, and for race skis i usually go with 1 and 3(side)... although my GSX's are at .5 and 3 after much deliberation regarding edge andgle. So, if you are confortable tuning them, remove the factory wax if there is any significant build up on the edges and bases. Brush the base and get them really cleaned up... it may require a hot scrape or two in order to get the bulk of the wax off. Then, tune them - not razor sharp - until you are used to skiing the ski, but give them a nice smooth tune to the proper angles. Brush the base again and make sure it is very clean, then apply two good base layers of wax and one final layer. Scrape or hot scrape between each one. The last one can be more thin than the others. Scrape and brush when you are done, unless you are going to let them sit for a long time before skiing them - then leave the excess wax on them until you are at the mountain or at least the evening before you depart.
If they are skis that you plan on racing on wax them about 10 times before applying the final coat - then wax and brush them every time you ski on them.
