Thanks for the kind words, much appreciated. Before switching to AF I used a mixture of products but mostly Auto Glym and Poorboy's products, but to be honest less and less Auto Glym stuff as time went on as I just felt that the products were not leaving the finish I wanted.
I've got Desire on the car at the moment and it's been on there about a month with just washes using their Lather shampoo, still doing the job on the car, what shampoo did you use on yours? Perhaps something stripped the wax? Their show car wax is very good, not as durable but gives such a lovely deep wet look for car shows! 
Not used much Autoglym stuff though I do like their Fast Glass which is excellent.
With the Desire, it definitely wasn't the shampoo stripping the wax. I actually did a half n half bonnet/front end wax comparison test - AF Desire v DoDo Juice Blue Velvet Pro.
Both sides prepared the same then the different waxes applied. All subsequent washes were with DJ Born to be Mild shampoo and both sides treated exactly the same. After just 2 weeks the Desire was already losing it's hydrophobic qualities and after 6 weeks it's was all but gone, whereas the Blue Velvet was still performing really well for over 12 weeks.
Here's the thread if you're interested
http://www.golfgtiforum.co.uk/index.php?topic=269693.0It shows the initial beading test video on the day of waxing followed by a second one (page 2) done a fortnight later which shows the difference in results of the two waxes. I just had higher hopes for it, but I'm more than happy with the DJ waxes I've tried, and Collinite waxes which are another favourite, 915 in particular
