'Ok do in my opinion a QD is the Swiss army knife of any range....
We are talking here about a QD rather than a spray sealant.
1) A QD can be used as a drying aid, a couple of spritzes on the towel then a couple on each panel really helps.
2) A QD can be used as a cleaner for rogue water spots after drying, bird bombs and light dust
3) A QD can be used as a gloss enhancing product
4) A QD can be used to provide some protection and a top up to existing LSP's
There are other uses like as a primer for a polishing pad, an aid to wax/polish removal and even a interior dressing.
Have a look at the following reviews which might answer any questions.

So the answer is, don't leave home without one'

'Like the polished bliss site explains it was first created to be used as a waterless wash but over the years it became all sorts:
- light dust and body oil (finger marks) cleaner
- water mark remover
- light protectant that lasts a few days to a spray sealant that lasts a few months (although the last ones to me are not considered to be QD- BSD and such)
- gloss enhancer
- interior cleaner
- drying aid
- clay lube
- window cleaner
- bird poo remover
- fresh bug splatter (not after a month) remover
- pad primer...
But mainly it is used after a wash as a drying aid to add lubrication to the drying towel. At the same time it also removes any left shampoo residue and water spots making the car appear glossier and thats why we love it.'
