The smell is ok to me. It has the same smell as the Meg's Detailer line leather cleaner & conditioner. For me, it reminds me of some kind of cheap, men's cologne. I much prefer the smell of the water-based dressing, NXT tech wax, Endurance Gel, and Glass Cleaner Concentrate. The only thing that smells worse is NXT Glass cleaner, which for some reason isn't necessarily a bad smell but it's the kind of smell that makes you feel sick after smelling it for awhile. Based on smell alone, I would give top honors to the glass cleaner concentrate.
the ASD has worked alright on tires with pretty decent durability. On trim, it sucks big time, at least on mine. I get better durability from Mother's Back-To-Black than ASD. I'm sure the type of plastics/rubber used also plays a big role because I like how ASD looks on my tires but it never comes out looking right on my father in law's.
I'm not sure if I'll get another gallon after I'm done with this. I've been trying out other products from different brands besides Meguiars. If you're loyal to only Meg's products (I once was, especially since I'm from SoCal also), you're really missing out because you'll find out that most of their products are just mediocre.
