The plastic door "recess" (on the top of the door) on my Elise cracked and needs to be replaced. I chipped the old one out but the adhesive Lotus used to affix it to the door had to be cut away with a knife which was not pretty. I would prefer to secure the new one with silicone sealant. Will this hold it in place securely?
At least in bathrooms, removing silicone sealant is a pain. after it dries nothing sticks to it and it is difficult to completely remove (which you have to do if you ever want/need to lay down new sealant))
I had good luck with contact cement. It's critical not to get any where you don't want it. To help with that I poured out some on a plastic sheet and let it thicken quite a bit before applying. You also might want to test first with just a tiny amount to make sure it won't melt the trim.
