<strong class='bbc'>Meguiar’s No. 20[/b] is great stuff. It goes on easy, and buff off easier than the <strong class='bbc'>Meguiar’s No. 26[/b] (the No. 26 in paste form).
One bit of advice I recieved from Meguiar's was to let it set up for about 15 minutes, maybe longer in cold weather. The residue it leaves is the same as any other wax I've used. Just keep turning the towels over to a clean side while you're buffing it off. <strong class='bbc'>waxman[/b] is 100% right - lasts a long time, beads very nicely, and two coats is a great idea.
I've used <strong class='bbc'>Meguiar’s Gold Class Trim Detailer[/b] with great success to remove any residue from plastic trim. One trick is to use the trim Detail on the plastic trim <strong class='bbc'>before[/b] you apply the No. 20 or any other wax, and then go over the trim again right after, before it gets a chance to soak in like <strong class='bbc'>Josiah[/b] said.
Let us know how it works out for you.
