w211 rear boot spoiler

[BIG_G_1979]

Hi guys I've ordered myself a rear boot spoiler (lip type) can anyone recommend a way of sticking it onto the boot lid? Some sort of foam tape or sealant? Any advice greatly appreciated also some that wont destroy the oem paint if I decide to take it off I I dont like

This is what I always use.

Can be messy if you are not careful but never dries rock (flexible) hard so can be removed without damaging the paint.

factory fit is 3m double sided foam tape, but it starts coming away so the sealant is probably a better bet
