I'm bucking the trend of favorable reviews here.I do give it two stars because it does go on easy, smells decent, and has excellent cleaning capability.  The towel came out more black than with other products, which I assume indicates it is removing a lot of oxidized black rubber/trim.Unfortunately, this product does NOT last.  I covered all the rubber/plastic on my car (two thorough coats), let it soak in/settle for a day, then washed it to get the overwipe/streaks of nearby body panels, etc.  The Meguiar's #40 washed completely off.  It was left worse than before I used the product.  The finish remaining was also very splotchy and looks bad.  Even some interior parts that I applied #40 to were mostly wiped clean after just wiping with a damp towel used to pick up accumulated dust/dirt.  It remained splotchy where there were minor nicks scratches in the plastic/rubber where more #40 had absorbed.Overall, I was very unsatisfied with the results.  I'm not going to say it is the worst product I have ever used, but others that I use are far and away better.  These include 303 Aerospace Protectant which is a very mild, water-based product which also doesn't last but is better than this Meguiars product and has almost no sheen.My previous staple and which I recommend most is actually Armor All Original.  I purchased a Guru Reports analysis on these types of products several years ago and was surprised that this "old" product was one of the two best-in-category products (along with Zaino) among over 50 that were tested.  Armor All Original (not other formulations) is very low sheen and also lasts several washes.  It is also about 1/4 the price or less and available everywhere.I'm going back to Armor All Original and recommend that you try it as it performs better than "boutique" products.  I would also recommend that you use water-based products on permanent trim, rubber, etc., as the solvent/petroleum-based ones have a tendency to degrade the rubber/plastic over time.  These may be OK for replaceable items like tires or parts that are severely oxidized.  You can generally tell the difference in that water-based products are milky color while the petroleum-based ones are clear.  I do like Meguiar's Hot Shine for severe problems, but not this product.
