Step 1: Use iron to drip wax down annd back on the ski once.
Step 2:Place iron on ski and spread wax evenly throughout ski, but if the iron is on the base for too long, the base will blister.
Step 3:Scrape wax off tip to tail.
Step 4:Use brush to remove any leftover wax, also tip to tail.
And you dont really need the wax on your tips, so that shouldnt be a problem.
