Give it a go man.
At Modded UK at Detling hill this weekend (which was brilliant BTW) my m8s bro brought his 5 door montego and he's done what ur saying.
He had the 2 rears and front passenger door handles filled and smoothed over, and painted. It makes it look a lot better, he does have to open the doors from the inside though!! He's also put his boot on a popper so he's delocked that as well. It does look brilliant!!!
