The other tip, which I’m sure has been covered, is when refitting the rubber strips into the channel is to put the ends in first and work towards the middle. I used a really blunt old flat screwdriver and lube it and do a small bit at a time.
Oh and I put masking tape along the length of the strips before starting to remove the rubbers, The rusty bits that fall out are sharp and paintwork easily damaged.
