Damit.... Now you got me on thinking with my mk1 escort mirrors, I bought Falcon xw gt motors which look like a deformed Ford mirror, was going to leave them black but am trying to reduce black add-ons. Won't do anything till doors and decals are on ..
Seen that link, swirl is the key for bhp after all other mods. D Visard shows this in his vids.
The badges are fglass of the originals I did from the 90s when they were everywhere, I still have a rusty Milo tin full of Escort/Capri/Cortina badges that were pocketed from wreckers back in those days.
RS and rally pack mostly had black badges but your car being almost black possibly have silver? Which ever colour I suppose the decals should match . If doing the satin back rear panel bit, it needs to be done right and watch a lot of The Professionals shows, mine was done wrong after a crash incident and I wasn't happy. In the end it's up to your taste and what you like, yours to appreciate and others to admire
