My husband had the same problem with adhesive stickers. Messy, inconvenient, and Doug said they ruined his paint. I got on the internet and found a company in Texas has magnets. They work very well and are very inexpensive. He carries the numbers in the glove box. When he got ready to run he'd just put his magnet numbers on the car and take them off when he wasn't using them. Plain, simple, and easy.Another advantage of his numbers is he is able to pick up sponsors and advertise of his car. Delco paid him 250.00 for the day. All he had to do was put Delco over his numbers. Doug is able to get 2 or 3 sponsorships per weekend.
Do a search for magnetletters. The company has a very nice product, and a ton of different sizes, colors, we got or order in 3 days. They have numbers, letters, and symbols ...
