Yeah, I'm on Optimum, Autopia, and Detailing Bliss forums as well. Like to get a wide variety of experiences. Thanks for the comments on the car, I've been enjoying it.
Yeah, I'm on all of those as well
(And a bunch more besides...). To be honest The Juice Bar and Detailing World are the best, but sometimes you'll see a good post on Autopia or Clean Your Car. Look out for threads that involve Todd Helme and Kevin Brown on Autopia; their posts on paintwork correction technology are worth their weight in gold, especially if you want to eek the best out of a DA.
I'm doing a ground-up restoration on a 1977 MGB Roadster, so you can say that I'm a bit of a British car fan
You'll really love BTBM (Amazing lubrication, excellent dilution ratio, great cleaning power, and a wonderful smell.), and I would also recommend that you check out Red Mist Tropical. It'll add a nice little bling to your car on overcast days and other low-light conditions like what you took that photo in, helps to eek out some time between waxing sessions, smells lovely, beads like mad, and is also quite good on glass
. Tyromania is a real hidden gem in the Dodo-Juice lineup, and would look very nice on your XJS due to the subtle finish (You'll also love the durability.). Otherwise Lime Prime and Light Fantastic are really great choices, and you'll be especially impressed once you can start playing around with LP on a machine. You can jewel it forever on a finishing pad, a little bit goes a long way, and it'll refine down to a lovely gloss...
