Paint help (again)

[GM]

Hi,If I want to paint 2k over existing paint is there a system for this? Do I have to bare metal? 

            Cheers Glenn

as long as you have a good solid base  i think you can go straight over the top as long as you give it a good rough up to give it something to stick to.it is good to go bare for the reassurance that nothing  will come up through your 2k

Thanks, existing paint is acrylic primer filler. I was told this paint "moves" and 2k doesn't.

Not a good practise to spray 2K over Acrylic primer it simply does not have good adhesion.. if it was mine I would get a pair of gloves and some scotch bright and wash off all the Acrylic primer with thinners back to bare metal and then 2K washprime it and then 2K prime it and then 2K top coat it....The Acrylic thinners used to wash it will not harm any filler you have used....The washprimer has acid in it to help it etch in to the metal far better than any Acrylic etch .....FC427........

wouldn't it be easier to spray it in acrylic and buff it ;D
there was no 2k in the 50's

[waynos]

Thanks all, yes I think I'll stay with acrylic now. Would be a big job removing all the paint. Thanks again.

Onya Glen, extra brownie points earned for authentic type paint ;D

FE & FC were originally painted in Duco   FB EK on was the start of Acrylic ''E Type "Acrylic then in the 70s it was replaced with the improved ''A'' Type Acrylic .......FC427.......

Is 'Duco' the technical name, or a proprietary one? :-\

[mcl1959]

Duco is a brand name, the correct name for the paint on FE and FC is nitrocellulose lacquer.
All paint in the 50's (and later) was referred to as Duco. Lines like "don't scratch the duco" and "give the duco a polish" were very popular as Duco was used on most of the Australian built cars of the period and became adopted as a generic name for car paint - very similar to the way Thermos is used for a vaccuum flask to hold hot water and Esky as a container to keep beer cold.

Also BALM paints were the supplier for Duco for FE & FC Holdens ....Last time I refinished a Holden in Duco I bought from a Holden dealer was late 70's I think it was discontinued from the dealers by early 80's but was still available from some paint suppliers till late 80's have not herd of anyone suppling Nitrocellulose lacquer in a long time ??? ??? ??? .......FC427.......

NC lacquers are still used in other industries, but not in automotive.  I know that you can obtain NC lacquers with UV protection for metal finishes, but haven't heard of these being used on cars or the like.

i remember seeing those cans when i was a kid,brings back lots a memories of my dad spraying his and his mates cars.
he would do it in a weekend saturday prep sunday paint.
i learnt very young how to mask a car.
back to the topic though,
you could paint her a matt or flat colour and there is no need for the blocking and buffing.
makes it way easier and the prep is also easier cause the imperfections dont stand out like on a shiny job.
