Cracked door top moulding

I have 2 front door top moulds on my golf that are cracked and not looking healthy, I know they are only around £35 each but I would much rather save that money and put towards something else if I can! 

My question is, has anyone had a go at repairing theirs? If so anyone got any decent pics of the process or tips for the best way to repair the cracks and spray up the moulds to look new? 

Thanks guys! 

Mend it on the back with wire mesh screen and epoxy.
Then use a vinyl seat repair kit to fill it in, and grain it.

Wipe with Alcohol and a Quick spray Krylon Fusion Satin Black… good as new.
