The more I looked at the lights with the dark black shiny smoked job I did, the more I agreed with Squozen and particlewave's comments...
I decided to try and get the lines back and get rid of the "painted on" look so I removed all the tint spray and re-did the job.
This time round I used a lighter smoked tint vinyl with a matte black finish so that it didn't get lost in the shiny black paintwork. I have also chromed the headlight corner units for more contrast and to give it a newer look which ties in nicely with the silver and chrome wheels, chrome exhaust and silver decals.
Sorry about rubbish pics but my phone is all I have at the moment...
