Careful with the D/S tape with the roof spoiler.... On the now dead n gone beemer, i used 3M's most adhesive tape, AU230 a roll, and whilst heading out to Malalah it flew off, almost hitting a truck after launching 20-30m high. Minimal damage, a few scrapes and chips, but i would have felt pretty bad had that truck come off the road.... he swerved enough to go onto the gravel, but corrected nicely.... I shat. Ended up sikaflexing it on re advise from a body shop.
