First things first
It is critical to start with a clean base and the best way to accomplish that is to hot-scrape with ReNew Zoom or (better) ReNew Zoom Graphite. To use time and resources most effectively, hot-scrape then brush and travel wax using the Renew Zoom of your choice. This way you will be ready to scrape, brush and iron in the competition wax.

The time element
Most world cup techs wax at night, then scrape and brush in the morning. If you do not have time for that, here are the minimum waiting times between ironing and scraping and the types of brushes recommended for removing the waxes:

	ReNew Zooms: 3 hours, brush with soft, fine steel
	yellow waxes: 3 hours, brush with brass horsehair
	pink waxes and Zoom types: 1.5 hours, brush with brass horsehair, polish with horsehair
	turquoise waxes: 45 minutes, brush with fine steel, polish with horsehair
	white waxes and Bullet: half hour, brush with fine steel, polish with horsehair

Some standard moves

	Always ask if they are making snow on the competition area. If they do, go with the new snow formula.
	If the night is clear, the snow will be very aggressive early in the morning. Go with the harder wax option.
	If the slope is facing north or west, the snow temperature does not change much from morning to noon, even if it is sunny.
	If the chance of new snow is around 50%, leave the antistatic wax out of the hot wax formula, then use new or old snow Race Rocket at the start for the proper antistatic properties.
	If you are waxing for parallel format, skiercross, boardercross, or halfpipe, wax harder because the wax has to last for multiple runs.
	Wait until you are at the start before applying overlays. This way you can make a decision after examining the snow.
