Gunmetal grey-TJ1 best colour match

I have used halfords in the past, but just dont think it was 100% colour match.
What can I use to get the best colour match to spray a black Gtir bumper in grey tj1.

What pre would be best.

Primer in grey, then grey paint, then gloss?

Help

Hi not too clued up on paints but I'm sure if you go to a paint shop ie resprayers they may be able to mix you some up.

Yes, thought about going to the paint/ spray shop. Just wanted to find out if anyone has used something other than halfords paint.
Unless I just order direct from Nissan.

I would of thought it would be grey primer for kh2 ... if its not right it will affect the base colour ....

Dont you have a local paint supplier? We have a company called john davey round here and his matches are next to perfect. Bearing in mind your TJ1 is 22 years old

When I sprayed my turini bumper the fresh grey paint was many shades darker than the original paintwork
