Ok, i did a search, but nothing relevent came up, so here is my question. I am ordering magnetic signs for my truck from a company online. I need 3 for the truck and 3 for the trailer. The trailer ones are going to be bigger. The problem is that they said, "You can't not use magnetic signs if there are rivets/bolts on the surface". my trailer is covered with rivets. What do i do for sings on the trailer? I can NOT have vinyl or Permanent signs becuase there is a rule in my area that i can't have a commercial trailer in the yard - period. This way, i can say that the trailer is used for personnal use, not for commercial. So, if i had magnetic signs, i'd take them off before coming home. Please let me know what options i have. Thanks a lot, guys.
