So I gave the Jayswax Showwax v2 ago and the gloss reflection is superb. Will get a picture up when I wash the car next.
My only (very) minor complaint is that it isn't the easiest to apply.
Having used Poorboys Natty's Paste Wax and also the Collinite 476 on other cars before, you need to apply Jays very thinly and evenly. As it takes a bit more time to apply, I don't see me using as often as I'd like.
I'm normally pushed for time to wax the car, but apart from that its a great wax.
