probably, for the amount of stuffing around its just easier to pay a pro a 100$ to do it..
I got a quote of 60$ to paint a bumper, 200$ to paint a bonnet so it shouldn't be too much to do some skirts..
I would buy a litre of paint though anyway so you have it there for future needs.It goes a long way, take it to the panel shop with you, they will have thinners and clear coat you just need to provide the colour
