Make sure your tires are clean and dry before applying. That goes with any tire shine product for the most part. I'd be interested in seeing how long this stuff actually lasts compared to a gel like Pinnacle Black Onyx. The last time I used an aerosol was probably 3 years ago and it couldn't hold up to rain and all the shine was gone within two days.
The one thing I did like about aerosol is that when applying it to complex tires (like larger truck tires) it was easier to ensure complete coverage in all the raised detail and lettering on the sidewall.
