Sounds like you're enjoying yourself then!
With your boot gutter are you going to fit any drain holes? The only reason I ask is that while I was in the garage last night getting used to my new toy I spotted some random tubes in the engine bay and when I followed them back they were connected to drain holes on the boot and engine cover seal shuts exactly like what you've just added. So I thought it worth mentioning, just in case as its quite spooky timing!
