Nice antenna. I'll have to try out the mothers possibly this summer.
fwiw, I've found the Griots Garage Spray-Wax very helpful and easy for maintenance waxing. In fact it's all I've had to use for the past year. Here's after a hand wash 2 days ago after hand washing 2 months worth of winter crap off. Notice the depth of shine and clarity of reflection in the reflection of the floor mat letters:
All I do is spritz a little of it on each panel of the Hoe before I take my waffle-weave Microfiber dry towel to it, and it shines while I'm drying it. So quick and easy. I've been really impressed with it. I just bought their jumbo bottle after using their trial-size.
Just wanted to share bc I found it's such an easy way to extend the life of all the hard work I put into keeping my black truck maintained.
