    C1 Chassis Finish

    It's time to complete the chasis on my '58. I've searched through the archives on trying to find out the finishes, inspection marks, and information on the black out process. Evidently there was a restorer article from the past that had this in it. Can anyone point me to which issue iit was in? Is there a listing of component finishes someone can point me to?

    I'd like to get the items to the factory finishes and then duplicate the black out process the late Dale Pearman describes in one of his responses. In one of Dale's articles he indicates using JD Blitz Black, but some else indicated that it was too flat. Any thoughts?

    Thanks,

    Ted

    Re: C1 Chassis Finish

    I used a product on my '56 called Chassis Saver that I bought from a local auto paint supplier. I'm sure you can find at any shop. It comes in gloss or semi gloss. I used the semi gloss, and you can shoot it right out of the can. The manufacturer says you can reduce it, but it's not necessary. I would buy a gallon just in case you want extra coats. It's about 70 bucks a gallon. It has just the right sheen. Jerry

      Eastwood makes a big deal about their chassis paint.

      Anybody have any comments on it?

        Ted -

        The original C1 blackout paint was an asphaltic mastic (P/N 3686683 "Underbody Protective Coating") that took forever to dry and didn't last very long, especially if the car was driven in the rain. For a restoration product that would last and exhibit the original appearance, Dale preferred a thin coating of gloss black lacquer, as he described in our joint C1 Chassis Restoration Workshop session at Bloomington in 2002.

          I use PPG DP primer as a base/primmer over bare metal including frame. I then buy a gallon of black PPG catalyzed urethane (chemical resistant) and a quart of flattening agent. I estimate the amount of gloss, semi-gloss and semi-flat (sheens by JG) paint needed to paint all restoration parts, estimate extra gloss, it can always be flattened latter if needed. If you have pitting, you can use a high build primer after the DP.

            John,

            Thanks for the response. I had found a response Dale hand on the tech board, back in 2002, on a Restorer article that had a list of the original finishes and he concurred with the finishes stated. He also stated that the article didn't mention the chassis blackout process that occurred just before the body drop and that would have covered at some level all of the initial finishes.

            I finally found the article he was refering to in the Spring 2002 Restorer. The article appears to be pretty complete on the various items that are painted (or not). I would like to first get the parts to the original finishes (or fair likeness using some of the specialty paints to prevent rusting) and then do the chassis blackout process. Since the article references a '60, I assume my '58 should have the same finishes. Is this a valid assumption?

            In Dale's response he states some of the chassis inspection marks. Here's part of Dale's response which contains the inspection marks. According to Dale,
            "The assembled chassis, with master brake cylinder sticking up on it's brake line, was assembled with painted components in various shades of black bearing inspection paint marks everywhere. Several unpainted components with paint marks also appeared such as the third arm bearing carrier, third arm, steering box, master cylinder, etc.The exhaust system, (pipes and mufflers) were coated with grease for shelf life but assembled on the car withoiut degreasing. The rear axle banjo had a large yellow circle painted around the filler plug if the car was posi with regular brakes, a large yellow "X" if it were posi with Metallic lined brakes, and nothing if it were non-posi or big brakes (RPO 687). A large yellow strip, continuous or intermittent, was painted across the top of the rear axle housing. The differential pumpkin had yellow on top of raw cast, black paint on top of that, and more yellow on top of the black. The tie rod sleeves had two yellow bands painted around one and one yellow band around the other. This on top of black paint. The ends of the axles had yellow on one end and white on the other. (two different lengths)Yellow stripes were on the shafts". Do you know of other inspection marks that should be in place?

            My understanding is the chassis blackout process took place from the top so some areas are covered better than others. My understanding is all of the suspension was in place along with the master cylinder "suspended by the brakeline". Do you know if the fuel line was in place?

            Thanks again,

            Ted

              Yes, the '58 was similar - same process was used. The chassis was fully assembled prior to body drop, including the complete driveline and fuel and brake lines; wheels were installed after body drop.
