Engine Compartment Restoration Help.
I'm pretty sure there was typically paint, (semi-flat black, done during what was called 'blackout'), on the fender aprons, the upper portions of the firewall, and in the wiper bay.
The blackout paint stopped on the face of the firewall about even with bottom of the heater box (which wasn't painted since it went on after the blackout was done).
The black out on the aprons extended forward to the core support, thus the hood hinges often had some black on them in addition to some body color overspray. The hood hinges started out plated, then received some body colored overspray, and then various amounts of black depending on just how well the 'mask' was placed for the 'blackout' operation.
The black out on the aprons began to 'peter-out' as the aprons turned toward the fenders. Generally there was very little if any 'blackout' in the areas of the aprons where the vacuum tank and vapor canister mounted on the driver's side on some cars, and where the washer bottle and wiper-door relay mounted on the passenger's side.
The 'blackout' was done quickly and easily (since the compartment was empty except for clips and brackets that were riveted to the firewall and aprons) since it was empty. The amount of 'blackout' varied from car to car just as the 'blackout' in the wheel wells varied from car to car. It was at best skimpy.... but was there.
Remember!!! the engine compartment in my pictures is a good example of what 'over restored' looks like! Use the pictures with caution!

I believe this is how bare the compartment was when the 'blackout' was done. The paint in this picture extends too far down the firewall, it should stop around the bottom of the heater box opening and the beginning of the toe boards. But I did it the way I wanted to do it.
Note the texture visible on the surface of the fiberglass.... no gel coat.

Yes, the Judging Guide indicates that points should be deducted for over restored areas/components.
I guess the most often used phrase is that cars/parts should restored to a condition/finish that would have been typical of factory production.

People use and like various paints, SEM, John Deere Blitz Black, Krylon #1613, Eastwood to name a few.
The fiberglass may be primed, but if it's nice and clean and sanded with about 320 paper, you can paint without primer. A couple of light coats should be enough.
Many of the brackets used to mount things in the compartment were painted semi-flat black too. But, since often those parts were originally painted by being 'dipped' they may have a little more gloss than the aprons or firewall. Depending on their condition you may want to use some primer.
It has been a long time since I did my engine compartment, I can't remember what brand paint I used, but I used low gloss black in a spray can. These days, for other parts, I like to use Duplicolor DE1634 low gloss black engine enamel.
As for the trans, the only "aluminum" paint I have used that looks somewhat real is Duplicolor DE1650 cast coat aluminum engine enamel.
I've never been too happy with krylon primer (top coats are fairly decent), just doesn't seem to stick as good as others.

Today I worked on the engine, although I only got half done. It would have taken way to long to polish up the M/T valve covers I had on before so I replaced them with some new ones I had for about 25 years.

Looks like you're making good progress.
The Krylon #1613 is still being produced but it's no longer available at the consumer retail level.
I order mine from a company named Film Tools. Even with shipping it's still a reasonable cost.
You might try some of the other suggestions.... people report good results with them.
Just stay away from the cheap 'no name paint' spray paint at the home store.
As I said in my first post I like the #1613 because I believe it's lacquer based so it re-coats and touches up well.

Thanks Bruce, I'll stop by there when I get the chance. Thanks for the reply Mooser, maybe the CTC store I went to was out of stock, I'll check another store.
Today I took more of the firewall apart and used a container of Spray Nine and scotch brite. Tomorrow I have a doctors and dentists appointment as well I have to run several errands so I don't know how much I can complete.
Progress Pictures.


The rubber grommets (such as the three or four hole one coming out near the throttle cable), if you can reach them from the inside, pop them all the way in and mask the cable/hoses etc off and stuff them inside an inch or two, much cleaner job.
Alternatively, if you run a trip or two of masking tape around the outside of the grommet and them pop them inwards just enough so the masking tape is in the hole it will make for a nicer job when you pop them back out. It's otherwise hard to get a nice clean line around them and it looks exactly like it was, a masked grommet.

Seriously, I buy it by the gallon when it goes on sale, I have found nothing better!
Great tip from Mooser about the aluminum foil, it is a real time saver compared to taping and masking irregular shapes.
Mooser, I agree, tin foil will work out great and I can get some for $2.00 at the dollar store, hey one time use.....why not. Thanks for the photo....what colour is that and is that the primer coat. Which year was that done?
Bruce, thanks for the tip, Spray Nine works like a charm and as you, I'm buying a gallon or two when it goes on sale at CTC.
I've order several cans of SEM Paint Trim Fast Dry Flat Black Aerosol 15.5 oz. 39143 as I've read it's one of the better choices. In the meantime I've decided to clean parts and work on body mount repairs which I've started new threads seeking more advice.
I was thinking of wire wheeling, degreasing then applying self etch primer below. I'm not sure what the top coat colour should be. By the way, the tank has already been cleaned.
These are the conditions of some of the parts although I'm not sure exactly how to refurbish them. I was thinking of replacing the seals in the booster but was told they're a bitch to seperate and replace so I'm on the fence.
