Outdoor Lighting - Velcro suggestions

Anyone know what you'd spec for super heavy duty outdoor rated Velcro?
I got one of the Harbor Freight 60 LED solar security lights on their big sale this weekend and I'd like to mount it between the door and window

It would be easy enough to back out one of the screws, run it through the bracket, and run it back in. But I think it makes the light look a little unwieldy - mess up the flow of the trailer, plus then of course I'd be driving with this whole fixture hanging off a dangly bit of metal.

I think it looks a lot better flush mounted to the wall. Plus then of course it's removable for travel if I use Velcro.

Any suggestions to what to look for in Velcro that will be permanently outdoors? I'd keep the light on it when not traveling for home use, so it would be working full time. I'm not even as concerned about the Velcro I guess as the adhesive used to mount it. Anything along the lines of VHB Velcro?
