As mentioned, the "hardwaxes" and "softwaxes" i would advise you think carefully before buying. They are not that great esp. when you take price in to account, if you search me username on here i have provided plenty of info before on the subject. You will get about 2-3 weeks where the product looks good, then beading thats worth your time looking at for another 6-8 weeks. NXT ver1 syndrome is what they suffer from.
The "Doublewax" is expensive, looks ok and lasts around 3 months. They expect u to keep it topped up as its a two part system, my conclusion; but some Zaino or Collinite! Cheaper and you dont have to top it up!
Supernatural, as again i have provided content for on this fourm and various others. 3 months of good protection, beading and looks. After that it slides off pretty quickly, may or may not have been extended due to the use Quickshine.
