My invaders dont hold wax worth shit, but they came factory waxed, so i rode them once or twice, then i waxed. if i dont wax them like every 3-4 times they stick so bad. if you go ahead and wax them, then i would try to take some of the factory wax of first, but make sure you dont harm the base. you might just want to put the iron to the ski and see what is on there. that might be a bad idea, i dont know.
