Is the Gardx product offered by some LR dealers any good?
Is it the same as the sealing product offered by some detailers?
Would you be better off having the vehicle detailed first then having a coating added?
Has anyone had it and what is your opinion?
Thanks in advance.

Tell the dealer NOT to wax it and take it to an expert detailer and get it ceramic coated. The coating can last up to seven years depending on which coat you use and how well you maintain it. Mine is Gyeon.

Worth every penny as it's a doddle to wash and looks better than when you took delivery, no swirls or horrible missed bits!!

I believe you have a good detailer in Essex as someone on here posted about him a few months back.

Thank you for your advise.
I think that is the way I will go.
I believe the detailer you mention is somewhere around Gidea Park which is not far away.
I will look back through some of the old threads for their name.

If you do get it coated, use this stuff to keep it nice and clean if it doesn't need a complete wash (like with the weather we're getting). It's brilliant and is literally spray and wipe off with a micro towel...Meguiar's G14422EU Ultimate Quik Detailer 650ml

Found the name of the company in Gidea Park 'Clean & Gleam'.
Will give them a call tomorrow.
Thanks for your advice & help.
