heat exchanger and motor paint
 
i have a morgan 37 with a perkins 4-108 motor. i have the heat exchanger out and want to paint it. currently it is grey. motor is blue. is this the proper color. also where do i find paint for the motor and heat exchanger. i want to touch up, but want to use the brush on paint to prevent overspray covering the bilge. what is the proper paint colors and where do i get that type of paint

Jason,

Can't answer about the "proper" paint color for a Perkins, but most that I've seen are indeed blue.

Really recommend you rethink your desire to use brush-on paint. Spray paint is widely available, and is much easier to use and generally with better results. You can protect from overspray problems easily by doing a good job of masking. Draping plastic garbage bags is a good way to cover large areas. Use paper and tape for smaller spots.

As is all paint jobs, prep is key -- do the best you can to thoroughly clean and degrease the engine before you paint.

Good luck,
PF

I would suggest that you look at the "Oven" paint selections that are available in stores like K-mart. High temp enamel with the most color choices at the best price.

Visit an auto parts store and get the high heat paint for engines, works good and drys fast

once again the spray can method will me much more difficult than you think and impossible in the areas i need it most as a spray can cant fit in certain areas and doesnt spray upside down. Does anyone know where i can find the brush on paint?

If you go to an auto paint store they can give you the paint in both a spray and in a can as well, so it can to both for you, make sure you tell them you want high temp paint

OK -- hadn't realized that space was also an issue (though I should have assumed so, I guess.)

This may work:

Re: heat exchanger and motor paint
 
Well some time has passed and i have the heat exchanger out and had it boiled and it is now bare copper and brass. I was considering leaving it bare. Is this acceptable? Will the copper and bronze corrode? Should i leave it as is or paint it?

Jason,

As coincidence would have it, I'm in the middle of rebuilding my 4.108 -- you may have seen the thread.

I did a lot of searching for the exact color match for the Perkins. I wasn't entirely successful, but found two spray can options that are pretty close: Duplicolor's GM Blue, and Duplicolor's Chrysler Blue. I used the GM blue on a few parts before I finally decided to pull and rebuild the entire engine.

Since the beast is out, I'm going to paint it with Eastwood's ceramic engine paint. THeir GM blue is a bit lighter than the Duplicolor, but I can live with it.

As far as your h/x goes, while it's off the block I think I'd clean the bejeebers out of it with a wire brush and good detergent (Spray 9 works well), then rinse & dry it completely (a heat gun can speed up the process nicely.) Don a pair of nitrile gloves, mask any areas you don't want to paint, then spray it down well with brake cleaner and let it dry. Prime it with an engine primer, then top coat it with your chosen engine paint.
