>>459514 (OP)>The business name AND products already imply for a design with squar (plastered)wall like shapes. So for the sides i made a square like shape in white spaceEven with this explanation I see nothing that suggests a "square like shape" outside of the logo itself.
FWIW a lot of people miss the point of fleet lettering/graphics...it's advertising but not the type of advertising most people assume it is...it's not a business card or display ad, it's more like a billboard and functions much the same way to create brand ID rather than to appeal directly to people actively seeking that service.
Consider that only X number of people will be exposed to this vehicle daily...of that number only a much smaller subset might be potential clients at any time and of that group only a tiny portion will be actively in search of a plasterer at the moment they cross paths with your vehicle.
When you look at that group, an even smaller number will be ready or able to grab a pencil or their phone to make a note of your contact info.
What *can* happen though is that with a memorable presentation even people who will never use a plasterer can be conditioned to remember your company name when the subject comes up. It's all about establishing name recognition and association with that business/work space...
In this case the clean/slick minimalist appearance works against you; I see vans like this all over and without your explanation I would assume it was for some white collar business service like a courier or document shredding and not a hands-on building trade....that is, if I didn't just tune it out immediately as one of a million fleet vehicles.
Which is another issue- even if I saw that it was a plastering company that ultra slick look gives the sense that it's part of a larger corporate entity and not a smaller company that might offer more personalized service.
Correct or not you have to consider those kinds of perceptions when planning this kind of thing.
