A few weeks ago I waxed my 2004 F-150 Heritage. It was a good idea too because a week later we started getting HAMMERED by rain. I have never seen a reservoir fill up faster in my life! Anyways, because of quick wax job, I got was on the plastic moldings on the truck. I've tried everything I can to get it off but it won't leave! What can I use to remove the dried wax from the plastic? And should I be using a nicer wax than Megieur's Gold Class liquid wax?
