I've had pretty good luck this year with a combo of Gyeon Q2Wax and a regular topping of Ethos Defy.
Went on a 900km+ trip last week and had no way of cleaning bugs off from the first part of the journey, so the car sat almost a week in baking sun with bug guts. Got home, gave the car a good rinse and then let my foam pre-wash soak for 10 mins... and they just rinsed off after that for the most part and no extra pressure/scrubbing during the wash.
Did the same trip last year but with a different combo (soft99 fusso + P&S beadmaker) and was left with all kinds of clearcoat stains that I had to polish out.
