If you want "any" paint to stick, you will first have to sand the shell, not scuff mind you, but sand.
120 to 150 grit sandpaper works very well.
To properly sand your 26 foot Airstream, plan on spending about 25 to 30 hours, to do it properly. Then you can coat the shell with an epoxy primer, and let it age for a few days.
Then, you can paint by hand, by roller, or with whatever tool you wish, and the paint will proper adhere to the primer.
How the paint will last in time, in the sun, with respect to not turning dull, depends on the paint quality you chose to use.
If you don not prep the shell correctly, your paint job, no matter what kind of paint you may use, will have a short life.
Lastly DO NOT
apply acid of any kind to the shell.
