When you absolutely need to paint the underside of the hood, but have no booth, space, or time to spray paint, get a brush and channel your inner Bob Ross.

The topside is gonna be finished and tires will be ordered tomorrow afternoon, and Saturday is the day we’ve all been waiting for.

Pretty sure the motto at the chemical plant I used to work at was “work harder, not smarter.”

Sounds legit.

Put a nice little turbo charger here, and we’ll just dab in a handsome clutch over there. See, anyone can relax in the garage with some paint and a performance state of mind? It’s just a swish here, and a dab there. Don’t you feel better already?

POR-15, or a can of chassis paint you had around?

Neither:

Got it. That stuff’s basically chassis paint without some of the fillers and thickeners - chassis paints are usually a lacquer, a heavy enamel, or a heavy oil-base.

Really? I’ve always wondered what chassis paint was. And now I know and I’m glad I went with this. I’m using it to touch up and cover many places. Fenders, wheel wells, floorpan...might even do the underbody because oil-based winter protection. I wonder if it’s possible to go overboard with this stuff.

Well, it’s what chassis paints have traditionally been. There are fancy things like epoxies now, and a lot of paints have hardeners in them and air/moisture cure beyond a “simple” paint like that RustOleum - although that being an enamel, it’s meant to harden quite a bit. A lot of RustOleum products don’t get all that hard and can play weirdly with other paints, but I think the brush-on stuff is pretty good there.

The last chassis paint I did a big job with was an alkyd lacquer, which is an “oil-based” (not really oil as such, polyester resin) lacquer. Not all that different than the RustOleum there. I put it over an incompatible rust prep, though. DURR. My Land Rover. I’ve had to repaint and retouch the frame over and over because the base layer made it flake off.

Chassis paints traditionally have to do a couple of things: stay black (resist sun damage, etc.), stay impermeable (resist salt and water), stay intact (hard and thick), and be cheap. For a wood chassis like an ancient Franklin, creosote does all that. For a steel chassis, it pretty much means hard, oil-based or similar, and with a shitload of carbon compound filler. Basic RustOleum pretty much has that covered, no pun intended.

SPI Epoxy is now UV stable for chassis/underhood work.

I’m spraying SEM Trim black on underhood stuff these days. Works well, but it requires a reducer.

When I do the Ranchero’s underside, it’s going to be in coal tar epoxy, because (a) no fucks given about a light lingering coal smell or thick layer, (b) it’ll do a better job of sealing than most, particularly small cracks and voids, (c) it’s extremely rugged, almost like an undercoat, (d) it adheres really well, (e) it’s good coverage for the money, and (f) it can be topcoated in body color in the wheel wells.

The hood will be something more traditional.

Its main advantage is it’s pretty idiot-proof and great value for the money for that job. Versatile. It’s what the guy who did a restoration of a ‘20s Ruxton in a thread on VWVortex used for chassis stuff, and that was a ~$120,000 resto.
