You don't need any equipment other than a liquid F4 glide wax. It’s all about how much effort you want to put in and what performance you want.
If you want the best possible results, you need different types of glide waxes, drills, Fiberlene, glide cleaner, different types of rotobrushes, wool and fleece, scrapers and an iron.
For example:
To use liquid glide wax, you'll need at least: Fiberlene, a nylon brush and a combi cork
To use heated glide wax, you'll need at least: A waxing iron, a brush, a plexi scraper, a scraper and Fiberlene.
