I had the WW spoiler installed, but it started warping in the heat. It came up about 2 inches in the middle, It was fixed, but it can't be guaranteed to be stuck down. Be careful if you want to buy it.
Be careful of where you park your car, my friend got three full panels keyed, very deep too!!

Did you just get installed? If so, no problem. Once it gets to bond to the surface, you should not have that problem. It happened to me the day after I got it installed. They checked it out and firmly pressed it back down. Its just a bonding issue! Hopes this helps......

Same prob here too. It starts to pull the double sided tape loose from the back of the real lip of the trunk when it sits in the sun too. Unlike ABS, urethane (I think) not very stable in the heat-moves too much.

 

I have had my WW spoiler for almost a year now with absolutely no problems, and I live in Hot-as-Hell Texas. I believe the problem you are having stems from the install. If any or both of the mounting holes on the sides of the trunk are drilled just a little bit too inward, it would cause the middle of the spoiler to flex up in the middle. But since there is double-sided tape to hold it down, it may look good until the heat starts to soften the adhesion and the spoiler flexes up again. I think the key is to mount the spoiler so that it will keeps it's natural shape without the double-sided tape, and just let the tape complement the bolts and aid in sealing. I don't think the problem is caused by thge fact that it is urethane. I had a WW urethane kit on my Integra for years with no signs of warping.
