ive seen omni shine beyond your wildest dreams, ive seen rubber seal shine better then others.
it all comes down to who is doing the work. if you wetsand/color sand every layer it will give you the best finish. Also the more coats you put on of clear and the straighter you make your finish the better the reflection. the product is only a small part of the equation.
who buffs it is also huge part of it. also what wax process you use is also huge part
as for truck listed above dont believe all you see, remember the amazing art of photoediting. a pos can look great in the right hands of a editor, not knocking his truck saying pos but just stating facts.
also if its a DD then why worry so much its going to be ruined the first time you wash it lazy. trucks like that are garage/trailer queens that only come out for shows
