I also like to take my Brinkmann and walk every panel on the car when I think I`m done. This way if there are any smudges, streaks, smears, etc. left behind I`ll see them and can fix them before I release the vehicle. Of course you can also just do an inspection under direct sunlight if your situation allows for it.
Only time I still can run into trouble is with a WOWA sealant if it hazes or streaks as it dries. Just the other day I had one I`d inspected thoroughly, then after 5 minutes in the sun some streaks appeared where the sealant flash dried too quickly.
