Dubplate Dan, thanks for the recommendations,

I have checked out the Chemical Guys JetSeal 109 and it seems pretty impressive, I think I will have to purchase some! Just a quick question, having recently waxed my car, do I apply two coats of this sealant after my next wash or is it best applied pre-wax, therefore wait for my next wax?
Also waxamomo, thanks for the link to the Dodo Juice Supernatural, excellent price!
I am aware that I may have jumped on the 'AG' bandwagon in previous years, despite being happy with the results and the more i'm getting into detailing the more I see there's a whole world of car products out there that I need to start trying.
One last question, if I do decide to purchase a second wax and wanted to apply this before my Col 915 has worn off, can anyone recommend a product that will remove any previous wax, contaminants, without damaging the paint?
