Chassis Semi-Gloss Recommendations
 

Back on the rotisserie, getting closer to paint. The painter recommended what he calls epoxy radiator black which is a pretty tough coating. I feel it’s a bit too glossy so any advice on a good product for the floor pans, subframe, wheel liners etc would be greatly appreciated. Jerry M’s book says 30% gloss for these items.

Additionally, I’m thinking gloss likely varied (as an example) between the subframe and floor pans as I assume the subframes came into the plant pre-painted. Is this a correct assumption?

Paul,

I'd reach out to Lloyd and ask him what he is using.

I looked through Chick's thread and did not see anything definitive as to what they used in his 68.

Can't wait to see the continued progress!

There's all you need to know about correctly finishing the undercarriage on a 1st Gen Camaro. Starts at Post #23.

Wow, I just read a little of that post and I am saving it to read fully and follow all the steps! I have a 51 AD and my 69 vert to paint and was wondering what I need to do. Those post are just what I needed! Mike's thread as well as Lloyd's Brooklyn thread, and Chick 68 Z thread are all you need to restore Camaros! :)

Bill Hirsch paints are high quality (at least they were 15 years ago).

The chassis black has held up very well on my car. I don't know if you can get it in a rattle can. But for me, even if you can, I like to use a spray gun.

Do they give full deduction points wise for using powder coat? It sure is nice and easy to mess with the sheens….

SPI Epoxy
 

Underfloor was done with SPI (Southern Polyurethane Inc) Black Epoxy
Notice the Sheen (Not Gloss by Semi Gloss)

Firewall Was Top Coated with DELFLEET Essential Single Stage Polyurethane mixed to the semi Gloss Formula

----Love that "semi" sheen, Chuck!.....Bill S

not sure if you can still get it, but gm had "reconditioning" paint in the gallon, corect semi gloss not too long ago

MY above SPI underfloor not only looks GOOD but is catalized 2k EPOXY......What's the Quality of YOUR suggestion ????

The GM #1050104 Chassis reconditioning paint is still available from several of the the specialty parts houses. Not sure if it is still the same formula as originally (or if available in gallons) but back in the day (mid to late 80's) at the Corvette restoration shop I worked at we used it extensively and even had a small-ish dip tank we used for brackets and accessories when restoring them. This was when people were just starting to understand the factory process for painting things and the restoration houses were trying to duplicate those processes - flaws and all.

In regards to Chuck's question about durability - probably not even close to modern paint technologies available today. Back then we'd use Sikkens Rally Black or DuPont Imron with a flattener if you wanted something more durable.

I use RM UNO HD SC804 for parts and components that call for 30% - 50% gloss, its a single stage product (catalyzed) that is easy to apply (read "forgiving"), durable, and once I learned the technique, I can adjust the gloss on the fly from the base 30% (out of the can) to about 50%. I like RM UNO so much that I've also custom blended it with RM UNO Gloss Black (SC403) for higher gloss finishes up to about 80%.

Thanks Lloyd, what do you use to raise the gloss to 50% ?

Mitch, it was a trial & error process for me (I use a Sata X 5500 RP gun), I spray a slightly heavier second coat (slower pass, full paint volume) at higher pressure (27 vs 25 psi) which brings the gloss up the range to closer to 50%.

Many thanks to all who responded. The UNO HD looks like it might be the ticket. I’m sending your posts via screenshot to the painter, Lloyd, much appreciated.

Gotcha, heavy second coat.
Thank you !

PPG Delfleet Essential is a Single Stage Catalized BLACK that you can formulate to various shades...................
