How to attach wing for moulding into the body

[PranK]

I have a small lip on the boot of the E90 and I've been toying with the idea of trying to mould it in to the boot to remove the gaps. I guess shaving the seams? No idea what the terminology is here. 

What I'm wondering is, if it's current double sided taped down, what would I do to more permanently attach it so it makes a good base for the filler? It only has edges so no way to bolt it down unless I add some braces.

I've done a lot of fibre glassing in my time so that's nice and easy but I'm not sure what my options are here. 

Sorry, this is the best pic I have and I'm 4 million ks from home ATM.

Sikaflex. There are many grades. I'm not sure which one is generally used for this purpose though.

That's kinda what I was thinking. Sand it all down and use something like that.
