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.
