Any decent quality auto was will do just fine. However you will want to clean it first to remove whatever sticky residue is present. Warm soapy water works just fine. You will find that the finish is much tougher than you would imagine.
As with Toad, keeping it clean with warm ver slightly soapy water on a microfiber is the best thing you can do. I would avoid waxing unless you end up matting (via rubbing/micro scratches) a high gloss surface (in which what you should really do is polish it) as waxed surfaces on the interior of a car can pick up dust.
