I've gone off poorboys lately. I find the blue paste wax doesn't really last long enough. Been toying with switching over to gtechniq sealant or the wolfs chemicals hard body stuff myself. If you already have HD wax you might as well stick with that until you've used it all. Be warned detailing is an epic money pit. Pick some stuff you like and if it works well enough for you stick to it and leave this area and never come back (before you get sucked in). If you must try another wax or you're running out of hd wax try collinite, seems to get good reviews everywhere and appears to be relatively durable.
