I have some great stuff for waxing cars but when it came to cleaning the AS, nothing seemed to work that well from those things. I do not know your brands. The clay bar might work. I started by reading up on what the material was on the finish. Think of it as semi-hard plastic (my opinion) I used some counter products like NuFinish Scratch Doctor, Meguiar's PlastiX and then Glare Microfinish and this other stuff that supposedly keeps dirt from sticking to the finish (got the last two from Airstream at a rally) I also use Bartenders Friend powder for the rock guards but wipe lightly in a straight motion. That REALLY cleans those up. I share this because so many products were ineffective on the stream.
