Me too! Thread hijack
I had considered using the guide to do it myself but it looks way too much work!
get hold of a 2nd hand one and do it yourself
then sell your old one on to the next person. i contemplated it and then decided not only would it be hard work to do, but you need to maintain it, which means the odd polish here and there to stop it tarnishing. with that in mind i bought a carbon plenum instead no polishing required
You can spray CF as well
