Hi Chris,
First, I think the car looks very good. Very red indeed, but it is not shocking to me, I really like it

You're almost done, congratulations!
I fitted my rear arches this week-end too, and I was wondering: what kind of trim/piping did you use between the arches and the side panels/rear tube? I can see a black lining there on your pictures, and I often saw that on finished cars, but I don't know what it is, and I'd like to put some on my car too to seal this part.
Could you please let me know?
Thanks.
