Engine paint .. 2k or synthetic enamel

[Andrew1967]

So correct shade engine paint is accepted as Mid Bronze green 223.

I'm torn between using synthetic enamel, as I've always used, or 2K which I haven't, on an engine/box.

From experience synthetic deteriorates fairly quickly over the years (although I guess there are good and not so good brands) and the engine ends up looking old and tired and in need of repainting.

I am tempted to use 2K over a 2k etch this time but may go with a good quality (HMG) synthetic.

Any thoughts or experience on the longevity of 2k on an engine in a car thats actually driven and used ?

Yep, 2K on engines is totally fine. It doesn’t discolour, shrink or burn off in my experience on either cast iron or aluminium, just a light dusting of aerosol etch underneath. Prefer to use PPG or Max Meyer over HMG etc as it seems easier to get a decent result(Probably more related to my lack of skill and facilities)

Andrew,

I asked HMG what I would be best using on a cast iron petrol engine. They didn’t suggest 2K. Their technical department will have answers as to the pros and cons of the two systems and I have found them very helpful (they even matched some Tartan Red no 1 in 2K for me).

Thanks Matt and David,

I've got both in two shopping baskets ... which do I checkout .. I've never been so undecided

Now if one was made in China, it would be so much easier to decide

Always 2K for me!

Just found a pic of the 2k painted engine being fitted that we discussed Andrew. It was a bit later than I recalled as it was 6 April 99.

20 years is a reasonable test still

[Andrew1967]

20 yrs would do me Andy

I'm not a 'paint guy' however, I understand that the faster drying enamels are the ones that don't last too well. Those that take a day or 2 are much better.
