@gmtechautocare_my: Watermark Removal Treatment with GM-TECH M-Series 1101 Liquid Foam Cut & GM-TECH Jitterbug Air Sander. Removing watermarks can be simple when you're using an acid based cleaner but can pose risks of damaging windscreens or glass that has already been scratched leaving a hazy unclear view through glass. GM-TECH Jitterbug Sander comes in a kit with Wool Felt Polishing Pad. The iron shape design makes glass polishing at the edges much more easier and less risk of damaging rubber edge trims. Using GM-TECH 1101 Liquid Foam Cut is one solution of removing watermarks without leaving a mess. For heavier watermarks, using GM-TECH GM-1 Fast Cut is recommended. Use GM-TECH Hydrophobic Glass Coating after treatment to repel water and reduce watermark formation on glass. #gmtechautocare #detailing #gmtechdetailingtips
