Hi. I’ve just bought new curtains for my truck and the hooks are stiff to say the least. Is this normal
WD 40 is your friend.
Or Mr Sheen (or equivalent )
if your not going to be doing nights out then its not a bad thing because then they wont move if you brush aginst them presuming your going to pull them half way across the window. 
Get some vaseline, at least you will have a good excuse for having it in your locker. 
Lol thanks
Let me guess, they jam as they come round the corner? Caused by the fact the curtain track is a straight piece, bent by machine. Look at it and you will see it narrows on the corner. Open it slightly with a pair of long nose pliers
Opposite. Tight on the straight bit and OK on bends.
