I have been using 1Z Anti-Insekt + Pre-Cleaner, but received Duragloss BR (Bug Remover) as a sample when I ordered my AW and found that the Duragloss made it easier (less wiping with less pressure) to remove bugs. YMMV.
Mark V makes a product called TCR It stands for transit coating remover, but also works fantastic as a bug remover. Simply dilute 3-1 with water, spray on front end of car, wait a couple of minutes, and pressure wash off. I use it every day in my detail shop.
