I have tried searching but can't find anything, The car was covered in ice the other morning (no garage), everything was frozen, windows, doors, door handles & boot. The door windows were frozen solid along the seal even after scraping and using de-icer, I believe de-icer rots the seals so don't fancy using it on a regular basis. What do you guys do/use, today I sprayed a cloth with silicone spray and wiped this around the door and boot seal but is there a recommended product. More importantly what can I use on the windows, I don't like the idea of the door window being frozen in place whilst I try and open the door Cheers Colin.
