orange paint best primer

[intransit89]

as it says is this orange best with white primer or gray
or does it depend how you want it brighter or dark i would of throught gray primer will make it harder to look right as in white would be about 3 good coats to look good but here is the link

you would need to do 3 coats with celly anyway ( with a light sand between coats ) and then need to cut and polish it to get a good shine so white or gray would work

have you thought of using 2 pack ? much less work and far more forgiving or if you dont fancy using the cyanide hardener how about 1 pack acrylic ? air dries over night and gives good cover and shine and will go over celly primer ok
