I am planning on tinting my side windows myself (not the passenger or driver front as I do not want the hassle, it is illegal where I live.) I read somewhere that the factory treated glass is about 20 percent, is this correct?

I am looking to see what % film you guys/girls have used to tint factory treated windows and maybe some pics to accompany.

I have been playing a lot of gigs in various places lately and carry a lot of music equipment, as well as camping gear that I want to keep from prying eyes, because you can still see through the factory tinted windows.

I do not plan on tinting my rear window as I would like to see when I back up.

Any pics or thoughts would be appreciated.

Thanks : )
