I am also on the lazy side when it comes to a separate waxing after the wash. Whenever I buy a jug of wash/wax, I just choose one that contains carnauba wax as an ingredient. There are usually several such choices available at any automotive supply store. I've already tried every one that's ever been made to date and honestly, I can't tell 10 cents worth of difference among the cheapest vs. the most expensive. I do spray the dust off my Ram with plain water in between washings, and never have I seen any "beading" of water droplets like you'd get with a real hand waxing. However, the lack of beading is not a bad thing if you are like me and don't shammy dry your Ram afterwards. The rinse water just runs off and dries up. But if your truck has a real hand wax job applied recently enough for water (rain, rinse or dew) to bead, it will leave water spots. My garage door is not wide enough to permit parking a full size truck inside, so it gets all that good hot SC sunshine and UV rays. Neither my 3 year old Ram, nor my previous 6 year old Silverado ever had a wax job, and I can't say that either of them suffered any noticeable paint damage, so maybe the wash/wax combos I've used did work, at least to some small degree. I can say however that if one does want an extremely quick, almost effortless hand wax job, then "Eagle Nano Wax" is the way to go. But the vehicle must be clean beforehand since Eagle contains no cleaner, and the process must be done on a regular basis....for example, until recently I owned a much loved 'vette' and I could completely Nano wax it in under 10 minutes,...do it in shade, hot sun will make it much more difficult.
