What ever you do, do not apply wax with a machine polisher!
Despite some common misconceptions, wax adds very little if anything to the finish, it is merely protection. All the results are achieved in the prep.
I personally like dodo waxes, specially rainforest rub as it is very easy to apply and remove, durability is fine. However for as good results and better protection I would go for a spray sealant like Auto Finesse Tough Coat. Really easy to apply/remove and it can be layered much quicker than waxes.
I have had various Swissvax and Zymol waxes in my collection but now use Tough Coat almost exclusively.
