Best tape for spoiler?

[heytim]

I'm trying to figure out the best way to re-attach/re-tape my OEM-like spoiler on my 3rd gen hatch. I previously used gorilla brand but it doesn't seem to last very well (tape is still very firmly attached to the spoiler itself, but not sticking to the car side anymore). Prior to attaching, I did wash throughly and wipe down with alcohol but it just doesn't seem to want to stay sticking on the car side.

So just wondering if anyone has any suggestions on which tape would be best/strongest. I'm thinking the 3M stuff, would this be good?

Or this? Seems less strong though,

I've read some people say that it would be a good idea to use an adhesion promoter, but others say it's not necessary and could damage the paint. Any opinions on if this step is necessary?

There isn't really a place to drill, nor do I want to drill holes into the car. So hoping of finding a strong/suitable tape solution.

TIA!
