Paint for my engine.

[MaranaF]

I have lifted out our old but very reliable Perkins 6.354 and attacked it with the pressure washer before the overhaul.

The question is... What's the best way to tackle the surface rust and what paint to use?

Hello I'm new here but last time I painted an engine I used hammerite, I think international manufacture a paint for this need

engine paint, removal..

problem with ordinary paint is that it will blister with the high temperatures on the engine block. yanmar and probably every other manufacturer volvo$$$, ford lehman, makes an engine paint that withstands the temperature.

as for paint removal, i'd go for a scraper and small wire brush on a drill head or dremel tool.....too much risk of harming seals hoses and gaskets with any chemical stripper not to mention the smell..

Some years ago I made a fairly reasonable job of a rather rusty MD11C by chipping, scraping, wire brushing and application of Jenolite and repeating the whole process several times before paining with Hammerite.

Jenolite because I had a large bottle and Hammerite because I had that too.


Frost or even Halfords can supply heat resistant engine paint.

I was faced with this quesion in the early 80's when I had a boat with a Perkins 4236.
For a profession in those days I painted vans with a brush and cars with a spraygun.
So considering that I was suitably qualified to paint my Perkins engine I found out that the paint was "Ordinary" Massey Ferguson Tractor Grey. The same engine the 4236 went in a MF165.

I used Hammerite on my engine.

Thanks all... I hate hammerite! Shan't be going that way. I thought it would be nice to find the original Perkins 'cream', any one any ideas on that?

Someone also suggested a rust treatment, has anyone tried any and would you recommend any?

Don't know why you hate hammerite - it can be got in a smooth finish you know....
My perkins is mid-green and hammerite is a match. I don't think heat should be a problem - it certainly isn't on mine (4108).
I use 'desrusticant' bought in Spain, I think it's dilute nitric acid (does that seem right Vic?)
It certainly does the job, and gives a paintable finish.

 

[MaranaF]

Why?

Don't know why you hate hammerite

Its a big brand, price to match and i am usually disappointed with the finish!

Engine laquer. Halfords do it and various other manufacturers as well. Degrease engine, paint, admire.

Bukh red engine paint and Hammerite smooth (or Smoothrite when I did the job) appear to be identical products. It lasted well after I did mine.

No it doesn't sound right but Google finds nothing for "desrusticant" More likely to be phosphoric acid based.

Another vote for Massey Ferguson tractor paint. Their red is very similar to Bukh original colour and cheap as chips.
Some years ago I bought a boat with a Bukh that although in good internal shape was a block of rust externally. I took it out of theboat, degreased it with Gunk, wire brushed it well, hosed it off and coated it liberally in Phosphoric acid to neutralise the rust. Washed it off well again and dried it in a warm room (SWMBO's kitchen). As soon as it was dry and warm I gave it one coat of Massey Ferguson red oxide primer and then two coats of red top coat. It came up like new and never rusted again while I had the boat.
I figure if that paint is good enough for tractors that stand outside all year round it would be ok on the boat.

tractor paint.

Tractor paint is the way ahead; find a local agricultural supplies store or tractor dealer. Tractol is a popular brand IIRC, but there are others.

Wots the engine Lakesailor?

T-Type MG?

"A" series 1380cc Mini. Sound feeble these days but it was 120bhp and was a lovely motor.

Use their primer for cast iron and then top coat of your choice. Did this with my Yanmar and then did a final spray with Yanmar paint - if you think Hammerite is expensive, you don't want to look at the price of the Yanmar paint.

Not sure why you don't get good finish with Hammerite, but in my view it is worth paying for it rather than put all that effort into a job and then cheapskate on the paint!
