No, it's super easy. You probably won't need more than one practice cart to feel confident. If you can use a pump or compressor you can use CO2. The only thing is it diffuses out of butyl tubes several times faster than air, so don't be surprised if the next day the tire seems unexpectedly low. Completely empty it and refill with air.
