I used 303 once on our previous motor home. As stated it worked fine on the gelcoat area which was acturally the front and rear cap. Any painted surface which was the rest of the coach and was not gelcoat it made it look like the side were just primed. Looked awful and what made it worse was rubbing the sides out to get it back to the shine I originally had. It was a lot of work. Now it may be good for vinyl, rubber or gelcoat areas but that's the only place I would dare use it. JMHO.
