The sunroof seal on my car looks white now, I think it has been scrubbed heavily by some sort of polishing machine...doesn't look like the natural color fade out due to the sunlight.
Anyway, I am planning to replace a new one.

There is a discussion here for the replacement DIY:

Just wonder who has done this before? anything need to pay attention to particularly?

I would try using some liquid-based products to restore the original colour before attempting a seal replacement. Look for a Meguiars or Mothers product at Super Cheap Auto (eg 'back to black')

edit: or even shoe shine haha

To clean window seal rubbers etc use a clean rag and metho.

This shall remove most of the polish.

To add some depth to the seal I treated my sunroof seal and windscreen seal with the dodo juice trim sealant.

The trim sealant is rather difficult to apply and is very sticky like a lacquer. It isn't really a consumer based product and would be classified as a detailers pro use in my opinion (you have to prep the seals first, then correctly mask off on paintwork to avoid the trim sealant from contaminating the paint as it dries hard like a clear coat)

Albeit once it dries it made the seals look a million times better!

It comes in gloss or satin.

P.S I've used mothers back to black and it looks great when 1st applied albeit its only a temporary sacrificial layer like say tyre shine, and after one or two washes it's gone.

this is how the sunroof seal on my car looks like.

I think the seal is damaged rather than having substance like wax residue, those black fiber is scrubbed off.
or the Mother black to black still can fix?

a brand new seal would look like this:

Hmm weird the seal on my sunroof is different to that I'm quite sure!

Unfortunately my car is in the workshop atm so I cant double check to compare I'll dig out some pics

[CYL]

the photo that I posted is OEM sunroof seal.
And I am pretty sure there is some sort of fiber on the seal rather than pure rubber.

yeah mine seems to be pure rubber/plastic, looks like the ECS item has felt on it ?

No Chamois for me.

I use a leaf blower and finish it off with a waffle weave microfibre towel, and some wolf chemicals quicky detailer spray

I've done it on an E46 before which is basically the same. It is pretty straight forward, a tip could be to get a pencil and mark around the screw holes to help you line it back up again.

Does the seal come it a strip or in a rectangular shape already?
It seems like it comes in a strip and need to seal it by myself.

Also, do I need to use any glue to stick it along the edge of the sunroof?

It is a straight strip from memory. I did it some years and 3 cars ago, it just pushes in.
