Did it at the weekend and pleased to report excellent results. Finish has a very slight texture to it which I think really gives an OEM look. Goes on well.
I cleaned with a brush and fairy liquid initially, then Autoglym extreme tar remover I had lying around which really helped removed all the grease.
Did top and lower grille, now thinking my fog grilles look out of place! Did my best to back-to-Black them but nowhere near as jet black as the sprayed parts now. Ran out of Autotek spray so will have to order another can if I’m gonna do them.
@shail did you do your fog light grilles as well?
