I've been using several Zephyr products on my 1968 airstream and couldn't be happier! There is a great guy named Robert who has been super responsive and really helpful in finding the right stuff to get the really rough corrosion. This airway worked great for pulling off some really tough corrosion on the Airstream BUT you will have to sand or go over it several times with another Airway/polish. Regardless it is working great on my Airstream!
Received the wrong stuff
