Bought a kit of 2 litre of ceramic coating spray heads and microfibre cloths for £10 about $12 on UK ebay.
Brand was " Pure Definition".
Previously I had to wash the car over each time I took it out to remove dust and bird ****..Have not washed it for a month. Water just blobs and runs off if you drive away .
Put it on and leave it just damp and it seems to take 24 hrs to "harden" so don't do any water test for 24 hrs.

 

I used a different brand and it's fantastic. Spritz a light amount on, wipe, turn over wipe again, done.

 

turtle wax Hybrid seems to work good for me,
