Are there something to use similarly than magnets but for aluminium or fiberglass bodies?

I'm gonna jump in and assume you need to change common messages frequently??
In America, our busses, (and also 18-wheeler trailers and some highway signs) have changeable messages made of thin aluminum within an aluminum frame, attached to the vehicle with screws . . .
They are sort-of in a book form and you flip-down and latch the message that you want to change too.
On a highway bridge, the Highway Dept. will change the signs accordingly . . .for example, you might see it flipped down in winter weather to say: CAUTION ICE ON BRIDGE
Another time they might flip the next panel down to reveal: 'CAUTION Narrow bridge', and so forth.
These same type vehicle signs will have generic messages that pertain to different situations commonly experienced by that particular vehicle operator.
Hope this helps!

Wow a quick answer! Thank you!
Actually my customer don't want to change message, but just to have a single message to use on occasion. He doesn't want something with screws and an empty frame is not necessarly nice too! May be the frame could be attached with VHB tape and painted in the same colors than the body.

Oh I see . . . Well, this particular sign I'm describing is a whole permanent thing containing up to 5 messages, and is screwed to the vehicle by the frame.
It also has a 'back' side when flipped up & latched that makes the entire thing flat.
Mabey you could fabricate something along the same principle.
Also, you could coat-to-match-vehicle colour, a thin peice of steel and glue it to the vehicle. (they make some really good automotive glues for body mould etc)
Cut to your magnet to size and attach the magnet to the painted-steel panel.
Just thinking out loud.

"rubber steel" is an adhesive backed material that is magnetically receptive. It has a nice smooth white finish that could be covered in vinyl (or paint, I assume?)possibly to match the vehicle color. Then a magnetic sign could be used on top of that when needed.
I got some at Product Sign Supply 1-800-540-9199

For fiberglass school bus roof caps I've made lexan signs for when they are sent on chartered trip.
I'm trying to think of the right name but you fasten the stem of the clip with 2 screws onto the vehicle to match the oblong holes you've drilled into your solid sign substrate (ie. lexan or sheet metal) then simply place the sign over the stems then twist the top of each one 90 degrees and the top part prevents it from coming off the vehicle.
These fasteners are very common on 'winter fronts' used on diesel trucks to keep them warm in cold temps. I wish I could think of the correct name.
Hope this helps a bit

Thank you all for your answers!
Doug, Is the magnetic strength of Rubber Steel sufficient for magnets on the sides of a vehicle?
