Let's try the Paint thing again

[ssbrewskyaz]

Can we run through this revised list again? I know I'm missing some key pieces. Feel free to add components to the list and I will incorporate into an attachment.

Ya know, until just now, it never occurred to me that some folks might want to keep this information a secret. But then again, it's not really a secret, it just involves scouring the internet until one stumbles across it.

Thanks for the input. ...SWB...

As with the frame, there are many different formulas that can be used to achieve a semi gloss black paint to match the factory finish. Some restorers like to mix their own paint to get the shine they desire, but many restorers also use a premixed PPG paint for their engine compartment. PPG 9423 lacquer is about as close as you can get to the factory finish. A quart can is enough to do a complete engine compartment. Many of the spray can manufacturers (e.g. Krylon, VHT) make a semi-gloss black that also looks good on, engine compartment components if you don't have professional spray painting equipment. If you have spray equipment here's another custom lacquer formula that you can use:

2 qt. PPG mixing black #386
1 qt. universal flattening agent
1 qt. mixing clear #3 10
PPG DTL16 thinner

Floor Pans:
The assembly plants used a dark gray to black finish on the floor pans.

Frame / Sub Frame:
The frame and sub frame were painted semi-gloss black. Some restorers like the frames a little more on the shiny side, while others like a flatter finish. There are a lot of different formulas for this and different paints you can use. Most restorers use acrylic enamel or acrylic urethane finishes with a flattening agent for frame components because of their durability, One formula that you can use is as follows:

3 qt. PPG Delstar rnixing black
1 qt. flattening agent
PPG DTR601 quick-dry reducer
