Repairing crack in composite door

[Postik]

Hi there,

I have a black composite door which is south facing and very faded. It also has a small hairline crack in it around 6cm long which I would like to fill.

I have searched for composite door fillers but cannot really find anything.

I wondered if I could use black Colourfill which I have used successfully on black laminate worktops in the past. I know that it is completely waterproof but possibly not weather resistant. Would it work or is there something more suitable?

Thanks,

Postik

Milliput might work to fill crack.
