Product tips?

[bmw528i]

Hello!
Me and my dad are wondering; we have tried many different 'wet tyre look' products. Most of them work really bad or only keep there shine a day or two.

Im wondering, what kind of products do cars in showrooms use? They are really shiny n' nice!

If you gave us some tips on some really good products that would really be great!

Thanks in advance!

the best one I've come across has been Mothers' "Reflections" tire care. It lasts longer than any I've used before and doesn't look like grease on a tire
