On every container of Zardoz notwax I think it is printed that it is the fastest there is. Using is believing. If you have the time and patience I highly recomend reading Zardoz's tuning techniques for teflon.
Pros- It is relatively cheap to use if your base doesn't need to be cleaned before apps.
Cons- you don't want to get your deck dirty then have to use solvent to remove the tar/ oil, whatever is on the bottom as it probably takes off to much Zardoz. This stuff is supposed to seep into the pores of your base. I don't like to drip $15 worth of teflon into the base on the first application then possibly remove a lot of it with solvent (Zardoz website should know more about this). The first app is supposed to be better to saturate overnight if I remember right. Then light apps before riding when needed.
