Engine painting advice/watchouts sought

Hello again,
Having recently lost my mind I thought I would repaint our Perkins 4-154 while waiting for the men in white coats to show up at the slip. Any advice or warnings for the collected wisdom of the board would be appreciated.

Thx in advance,
Ike

I took my motor out, had it shot-blasted, zinc-sprayed and repainted. It looks good, 11 years on.

Don't get the shot blast material into the motor.

I started on the same by using Rustoleum rust reformer on all the rusty spots. Works well. Haven't started the painting yet.

There is another thread from just last week with some good tips on painting. Try a search

An engine rebuild kit in a can.

It's pretty straigtforward - use a spray can, tape off what you don't want painted and paper off the engine room.

Thanks Xort and Nola. I hadn't thought of the Rustoleum to lock up the rust I couldn't get to. I'll be doing this in place so taking a page from NOLA I'll be masking everything for miles around. The Admiral will have my a$$ if I get paint on anything other than the engine!

Ike,
We painted our old Perkins4-108 nine years ago (repowered last year-but the old Perkins was still pretty when we donated it)
The two tips I gave on the last thread I think are worth repeating...
1. Use aluminum foil to mask off hoses and wiring you do not want to get paint on. MUCH easier to handle and shape than using plastic and tape and very easy to remove.
2. For areas you need to use a brush-spray the paint in an old container then use the brush to dab it on. There are those places where spraying just isn't a good option.
3. Spend most of your time prepping-it makes a huge difference in the final product.
Good luck!

How essential is the priming paint, and what exactly does it do?

It usually contains a rust inhibitor and bonds better to metal than the top coats.

Thanks Martha, I will search for rest of your thread. I like the Al foil idea!

I've removed the reservoir, water pump, heat exchanger, oil cooler, and a couple of pipes, from my 4-108. After internal cleaning I am now painting them using Depco engine paint and primer. I was using a Ford blue, but just bought a GM color that is similar to the Perkins blue.

The reservoir and heat exchanger just got engine paint, the Ford blue.





The oil cooler and pump have been primed and will get the GM Blue engine paint in a few days.

I spent a day last weekend attending to the block - much easier to get to w/all that other stuff off. Cleaned it and scraped all loose, flaking paint off and began using a rust-off treatment in areas. Need another day of prep on the block. I'm not going to paint the whole thing. Just touch ups here and there. Too cold to do more. But I can keep areas warm with heat lamps.
