Engine paint

I've just got my injectors back from having new jets fitted and for some reason the workshop stripped them of paint. Do I need to repaint them and if so, will ordinary gloss do?

Surely your joking?
Outboard spray or heat proof engine paint.
If your not joking use toys r us kids paint.
 
Question - when re-painting an engine, how do you de-grease so the paint will stick?

Not sure I fancy having the stink of Gunk in my bilges.

Jizer is the stuff. It don't pong as bad as Gunk. However, it is still an emulsifier so the hydrocarbons will still end up in the bilge.
Buy a pack of disposable nappies and lay em out under the engine to soak everything up.
 
Gloss or Matt Sir ?

If you take a small sample of your paint colour into your local paint factor,they will match the colour very closely(VILVO green in my case)but the important thing is you get a full litre tin of brushing paint for about the same price as one of those tiny weeny little spray tins and of course you can use the paint to get those other jobs done without coating your entire engine room in overspray.
 
Red Hammerite Smooth (Used to be called Smoothrite) appears to be exactly the same stuff as Bukh engine paint and a fraction of the price. However the injectors on my Bukh were unpainted. The ones on my Yanmar are painted, as is everything else including the belts. That paint doesn't appear to be anything very special.

Beware - I once bought a can of red Smoothrite to repaint an outboard fuel tank. It looked smart until I tried to fill it when it all dissolved in a bit of spilled petrol. I don't know what effect diesel or oil would have but I wouldn't let the stuff near my boat again!

Absolutely right.

I found Hammerite very poor for resisting fuel, just like most paints.

For best durability and heat resistance I always use engine lacquer, available quite cheaply from car accessory dealers. Here's my Volvo petrol engine repainted (by brush) with "Carplan" engine lacquer.

To clean the grease off, I use a small refillable hand sprayer with any water soluable degreaser, then rinse it off with a large pump up garden sprayer, the type with a lance. Then I use an engine oil sump pump to suck it back out of the bilge to dispose at home.
 
I have my md1b engine resprayed with tractor primer and tractor paint. I chose Ferguson grey, but you can get Ferguson red, Ford blue, John Deere green, etc. etc. :D
It is heat resistant and pretty tough stuff. Degreased with regular engine degreaser but it was outside the boat so it got a good wash down after too.

Hammerite ,even when hardened, washes off with petrol and other petroleum products. The Bukh engine paint is clearly not the same.

Thats the stuff, Sticks to everything, cheap, easy to spray and lasts well, Done a good few engines with it, Its made to paint tractors after all.

Recently there have been several posts that suggested that Hammerite was no longer the product it used to be. My experience on my Bukh engine is about 10 years old, at which time it most definitely did not dissolve in fuel and was identical to Bukh's own engine paint. I can accept that it may be different now.
 
Shorebase, impressed, very tidy indeed, I am not surprised you wanted to take a photo of it.

My wife thinks I'm an anorak though, but I can't help myself !

Re the further comments on Hamerite, I've found that all the current varieties, (smooth, hammered, sprays,tins) do wash off easily with petrol, even after the 30 days of curing.

Even the engine lacquer that I used does need some time to harden up before it's resistant.

I am a fan of Hamerite otherwise though, great for metalwork in harsh situations, requiring minimal preparation and no priming.
