I am a HUGE fan of Meguiars but hate their 3 step process.

Try my old stand by.......you'll get much better results and much less work.

After you wash your ML... Apply Meguiars CleanerWax (Burgundy bottle)....if you get a smooth glass feel, your done with the first step. If not...apply it again.

Next, apply Meguiars Gold Class wax as a top coat(Black bottle in a box).....You will get an awesome wet look shine (if your ML is smokesilver you will think I am the Wax god!)

I have tried all the others including the 3 step. I was very dissapointed in the 3 step especially how long it took with fair results.

I hope this helps!
Good Luck!
Mike
