Sharp scrapers are key to a good wax job. Buy several of those
scrapers or equivalent all at once. You'll thank me later! A scraper
only lasts for a few wax jobs and they need to be completely clean to
work right. You save a lot of work with a sharp scraper.

Personally, I use paste. Start with a good hot wax and paste can keep
you going for weeks. I like F4 and toko because the dry on hard and
rub in.
