Best way to secure boltless Duckbill - Ducktail Spoiler?

[WaffleMix]

Anyone have any experience with a spoiler that doesn’t use bolts to secure it down. I will be installing a cheapo duckbill spoiler (until I can save or make up my mind for the spoiler I really want, I do love the look of duckbills). I am just looking for some recommendations and the best way to secure it to the rear trunk without it flying off on the highway. I know of 3M VHF and adhesion promoter but don’t know of anything else. Also I must be looking in the wrong places but where can I find the 3M VHF and adhesion promoter locally in the states? If there are any other ways to secure it that would be great. TIA
