As a part time detailer, I do one car/truck or SUV every Saturday (weather permitting) - I don't have time to screw around putting 5 layers of LSP on a vehicle. Like David F said, you could use Turtle Wax with simular results. When I first got into detailing and maxing the credit card at Autogeek and other on-line stores, I thought yeah, I'm going to wash, dry, clay, wash, dry, polish, and do all those sealer - wax etc applications. Well, maybe if you have a trailer queen show car and hit the circuit every weekend. But, for most of us, a nice coat of DG 105 or WG sealer looks really nice if you've done your prep work right. Now, I'm not knocking Blackfire, or Zaino or anybody that has the time, energy and patience to do 5-10 layers, that's just not for me. I like sealers, tried the legendary Natty's Blue on my Flint Mica Rav4 after I had used WG, wasn't impressed and wound up stripping it off and using DG PBA and 105, and AW every month to keep it looking good.
