Armor All Extreme Shield Max vs.Maquiars Ultimate Liquid wax

The best product is the one you use often .
MeGuiar's Products are what I use a lot now .
Frankly , there are plenty of good products .
The main thing is that I wash my cars / trucks at least 40 times a year .
Clay bar for car finishes annually .
I thoroughly wash my trailer after every trip without exception .
For the trailer ICE and NuFinish work good enough .
I make sure that I have washed my vehicle thoroughly before polishing , as instructed .
