Hi i have fitted some new window channel in my ford f350 truck but the glass is very tight when i wind them up and down.I did some repair work on the door channels so i must have made it smaller.So can i grind,rub sand polish the door glass edge.It has rounded edges.I need about 2 mm taking off.There is a name on the glass but i think its in dutch so it might be toughen glass thanks again

I've known people manage to SLOWLY thin toughened glass but it can set up heat stress and make it pop for no ( apparent) reason. when no one is even stood by it. 40 grit on a DA with water soaked rag near edge to stop heta spreading. Eye and breathing apparatus neccesary .
You could give silicone spray in the channels or melted candle wax a try first.
