Hot wax

take the iron, melt the wax by putting it on the iron, let the drops of wax fall on to your skis.  Then take the iron and smooth out the wax on ur skis so that the entire base is covered with wax.  let it dry then scrape. 

how focused do you want to get?  if not super focused bring your skis in the house so they are room temp.  Make sure you dont heat your iron too hot.  It is too hot if you smoke out the joint.  drip your warm weather wax on your first ski (up the full length). Then iron it in.  Keep the iron in motion.  If you leave it in 1 spot you can fuck up your bases. Generally people will drip too much wax on so be careful not too.  Cool and scrape with a plastic scraper

If you want to get super focused you will need a brass brush and a horsehair brush. let me know

heat up iron. drip on wax. smooth it out. let it cool. scrape off.

on this forum its best to stick with the basics people are telling you all the posts above are pretty good for keeping it simple. a lot of people here dont know what theyre talking about so watch out.

watch these videos and they'll show you how really well
