So, After much deliberation on what to do with my engine cover and how to go about it, I decided on some high temperature engine paint in a graphite grey finish, and a high temperature engine paint clear coat.
A picture shows the colour before messing around, a weird beige that in no way fits with any part of the car?
After a few coats of graphite :)
After its been fitted with about 5-6 coats of clear
Finished picture isn't great, however it matches my car colour very well actually in normal light, which was my hope!
