No offense but i think magnets make you look like a "fly by nighter." The only magnets i have is on my Toy truck...Its my recreational truck in the summer and plow truck in the winter...Thats the only time i throw the magnets on... All the other trucks are just lettered on the side windows. With the company logo and USDOT #. Not a fan of all the lettering anymore. Bought a trailer COVERED in lettering for a STEAL! Pulled all the lettering off and used this Contractor's Solution that i got from my lettering company and all the remaining adhesive came off.
