Hey guys, since buying my BA a few years back its always had some quite bad water droplet marks that just persistently remain on the outside of all my windows no matter how much windex and elbow grease you add... So today I decided to do something about it, did a little research and came up with using Metho to scrub it off- No luck at all... So further Internet browsing led me to a product called SPOT X. It's primarily used for shower screens etc.. Went to Bunnings and they sell it for $23.. Holly crap does it work..!!! Took me about an hour of scrubbing and following the instructions, being careful not to get too much on my paintwork and followed it up with a whole car wash just to be safe, ill attach a photo of my windows before and after the SPOT X, keep in mind the window on the right is cleaned and shammy'd and that's as good as all my windows previously got... Not sure if anyone will find this helpful but it worked too well not to share it around for you guys.... Makes my window tint look even darker now as you get an insane mirror finish on it. Cheers fellas!
