I had the idea to coat the outside surface with synthetic motor oil to deny the raw surface to the taggers and we have done this. A neighbour 3 doors away has a persiana that was tagged, permanently. I'd post the pic but don't know how.
In any event, I didn't know that in addition to the difficulties of finding good construction help here I'd be trying to outfox vandals. I'm thinking that the mosquito device along with a motion sensor will probably be the best investment I can make until I'm in Chile full time and get a dog.
And as for the "art" aspect, if it's been requested, fine but otherwise it's vandalism and should carry a mandatory 6 months on a cleanup crew and a big fine. We'll see how much disposable income they want to use on spray paint after that.
