I used 3m body trim tape. It has held strong for about 8 months so far. I have a ceramic coated ppf on the front.Did you end up trying this? Did it work? I just can't bring myself to having the front bracket screwed into the bumper and so i'm looking at going the adhesive tape route, too, to mount the bracket. Something that I can remove later on. But also don't want it flying off when cruising down the highway.
