I have ALWAYS used 3M double sided tape for spoilers, splitters, fins, diffusers and have had ZERO problems. If it is applied correctly, it WILL NOT fly off, even at high speeds. If it is installed incorrectly it could fall off in extreme heat or cold.
TO install correctly the tape as well as (both) mounting surfaces needs to be heated up with a hair dryer or heat gun before mounting.
+1 Have had my perf spoiler on for almost 2 years using 3M tape and it's still rock solid.
