Hi Terry,
as to the correct colour of Holden grey engine enamel - I think it is quite varied - from Massey Ferguson to Castrol green....................
Depends what they had on for the day -
You will see many varied "greys" - no one, I believe, can say any grey is wrong.
I found a supplier here in Melbourne who prolifically states they have the original code................
The supplier I got mine from is Eastern Auto Paints p/l
2/20 London Drive - Bayswater, Vic - 3153
ph (03) 9761 2155
Fax (03) 9761 2144
their product code is 363-G2X1 - don't know if there is relevance with that code to another firm - I believe the prefix of 363 relates to auto enamel
I asked as to whether it was heat tolerant for engines - I was told it is just normal auto enamel - mine has not suffered in any way from heat or chemicals (oils, fuels etc)
The colour is a greenish grey - if you have a peek at the sump in this pic - will give you an idea by what I mean "green" grey - it is sort of a Castrol oil green (some would say that GMH used it to camouflage any leaking oil)
We have a few in our club who have chosen this as their "grey"
I think it is probably worthy to state that if you do get some mixed up - keep the code so that you may match it for future use.
I used a 1k etch then acrylic primer prior to laying two coats of this on my engine components..............
hope some of this helps, Terry....?
frats,
Rosco
ps - if you can't get it mixed in an aerosol - try Bunnings - they have the "Preval" system - cheap little set up that permits "aerosol" application of any type/colour of paint.........
