Can I use Veet on a 7 month old scar? And can I also use wax over it?

I got a tummy tuck seven months ago and I was wondering if it's safe to use Veet gel or spray over my scar. My scar is not white yet, it's a faded dull red color if that makes any difference. Also is waxing over the scar safe? My reason for body hair removal is because i'm into bodybuilding.
