If you're going to go the route of using the window tint film and doing it yourself, here's a few tips that i recently learned from trial and error. ( yup, you get to learn from my mistakes... you lucky dog. lol ) Pick up th edarkest tint that you can find, ( my wife got mine at Walmart, it's 2.5 percent and you can't see my nose or anything else inside of the helmet. ) Make sure that your visor is curved into the position that it'll be once re-installed/installed in your helmet. ( I tinted my first visor I made while it was still flat, then watched with horror as the tint film crinckled when I curved it to install ) Cut your tint film larger than the visor ( as per the instructions ), and wash your visor with luke-warm water and some mild dish soap. If you have a spritz bottle ( like the kind for misting house hold plants ), fill it up with water and add a few drops of dish soap. Place a towel down on your work area, and spritz the soapy water mixtuer all over the visor. ( on the side that the film is to be applied ) Carefully peel off the backing to the film to reveal the glue and spritz the glue side of the film with your mixture as well. Carefully position the film on the visor, and gently ( working from the centre out ) press down the film with a rigid edge ( I used a tongue depressor, but a popsicle stick should work the same ) wrapped in a clean lint free cloth. Spritz the visor and tint again with the soapy mixture, and gently sqeegee the bubbles towards the edge of the visor. Once you're satisfied with how it looks ( getting the majority of the bubbles out that is ), trim the edges of the film. You're now ready to install the visor and go about happily trooping with out having to see eye-to-eye with any one. ( unless you take off your helmet that is. )
