Holy cow this stuff works and works fast. I used masking tape to protect the surrounding paint and just used a microfiber towel and rubbed it in by hand. I spent maybe 5-10 mins on each headlamp and the results were fantastic. I restored the headlamps of a 2007 Honda Fit and a 2004 Nissan Maxima. The honda fit turned out great but i'll have to retreat my maxima since it needed much more work. Highly recommended.
