I think so, I've been asked several times what I use for wax. Didn't have the interior done.
The product my dealer used has a 5yr warranty against faded decals, if also has a retreat clause, if needed.
All I can add is a lot depends on how you feel about your dealer, in my case been using the same one since 1977. The same applies to the extended warranty. If it's backed by the dealer with a 0 deductible at their facility and a pro-rated refund, no reason to be skeptical in my opinion.
