Stroke it gently and it will eventually raise up.

 

Simple

 

I just LMFAO'd at this whole thread

 

charm it with your flute and it will slowly raise up

 

This should do the job....

 

Barry White, massage oil and a bottle of vintage Dom.

 

Should have bought one of these, no need to raise them!

 

Try using a host that isn't shit.

 

Have someone sit on the back when you're driving really fast in the rain with a bottle of shampoo in his hand and a toothbrush. When the spoiler raises up, have them squeeze some shampoo underneath then drink a Red Bull, scrub the shampoo around with the toothbrush in a circular motion. Most likely by this time you've run out of roadway. Turn around, and repeat. On the third pass, have the person on the back (preferably a woman) take their shirt/blouse off and wipe underneath the spoiler until it's dry, still holding the crumpled can of Red Bull in the other hand.

 

Wow.....thanks for all the useful replies......
