Title: Engine bay paint break
Post by: aaatp on July 12, 2010, 02:59:10 PM
My painter is getting ready to paint the engine bay on my 66 Dearborn convertible and I need to know roughly where
the paint break would be. I'm thinking from the firewall forward including the oustside of the fender aprons or should
I say in the front fender well areas including front frame rails, and the radiator support, front included.  I have before pictures of my car, but since it was primed in black, I have no idea where the break should be. A picture would be handy.

I was going to use PPG DAR 9000 flatend to the "eggshell Formula" as per Charles suggestion, but apparently PPG
does not make DAR 9000 anymore. My painter has come up with a substitute from PPG that replaces DAR 9000, but was wondering what you guys are using if you cannot get DAR 9000 anymore.

Thanks Guys: John

I am not a expert on the 66 models however I think they used the same type of engine blackout up to 73. On my DEARBORN built 69 I used STANDOX rally black, its a two part urethane product paint & hardener. If you spray it out of the can it has a nice low gloss finish that looks correct and is much more durable than the original was. You can reduce the product if you want or add gloss black to make it more shiny however in my engine bay I just sprayed it right out of the can and I am happy with the gloss level. As far as the breaking point in the aprons on my 69 it was faded out at the front of the transmission tunnel. the inside of the frame rails were also faded in and the core support painted on the front and back side. Mine originally was pretty sloppy and probably just one heavy coat. I decided to do a little neater job. The underside of the rails & radiator support should remain primer or undercarriage (slop) color. Again this was on my 69 & there may be some slight variances in application on the 66 model.

John - lets start with the basics (since when and where can make all the difference ;) Plants differ on this process (engine compartment transition to body color) and even changing at the same plant (like 69) part way through the year based on ALLOT of original paint pictures


When was you car built at Dearborn?

Typically we see the line/edge finished with a brush that year on the top edge of the inner fender panels, but repost with the info and we should be able to post some examples from the same time period.

As for the wheel side of the inner fenders - well we can post some of those also - again very different from both the other plants (Dearborn)

Jeff: Sorry about not being that specific, my cars' proposed build date was February 18th of 1966.

Thanks Again: John

John I have a '66 Dearborn coupe with a scheduled assembly date of June 11, 1966. It has the "brushed" paint break that Jeff mentioned. Here's a shot of the passenger side to illustrate:

As you can see, the brush strokes are very prominent towards the cowl and go across the inner fender. Hope that helps ya!
