Replying to Ski wax help!

So I'm planning on getting all the essentials to waxing skis soon and was looking at wax the other day. Can I just use any type of wax, or is there a specific type of wax for park skiing? Would it matter if I used wax for race skis?I also noticed that they sold wax according to different temperatures. Does it matter if i use the wax meant for a cold day on a warm day? Also is there a specific way of waxing park skis, or is it the same for all skis? Thanks for the help!
