I am rebuilding a late NH carb. I plan to apply a prime coat and a black finish coat. What is the best way to apply, brush or rattle can? What is a good paint to use? I plan on using Rust-Oleum.

Just use your best judgement… sometimes just wingin’ it is the best way to go…

In case you don't have rebuild instructions https://modeltfordfix.com/rebuilding-th ... el-t-ford/
I'd use Rust-Oleum Automotive Engine Paint is good enough for any heat concerns. Plug all holes see instructions on rebuild.

I used engine paint, primer is already in it.

I don't paint them at all. That way it can't be attacked by fuel.

Model airplane fuel proof dope works well. I use it on model A gas gauge numbers which are submerged in gas.

I've always used rattle can Rustoleum satin black. I dislike glossy paint on chassis parts. The Rustoleum doesn't need a primer.

Since this pictire was taken I've painted the filter. Same paint.

I use black lacquer in a spay can. Gas will not attack it. no primer.

I had a half dozen NOS carbs several years ago, and the bodies were probably black parkerized originally. Not sure what they called it way back then, but it was a rustproofing treatment that left the bodies with a dull blackish/gray finish. NEVER painted. This can be easily replicated if you check on line, lots of easy methods. This all if you want original look. Otherwise, paint away

Rust-Oleum Engine Enamel Spray Paint is a high temperature engine paint protects your engine from the harmful effect of heat, oil, gas, grease, rust, salt, solvents, and humidity. It is made for manufactured for the cars’, bikes’ as well as other automotive engines. Rust Oleum Engine Enamel Spray resists high-heat up to 260°C and gives a smooth finish to your engine surface. This forms a long-lasting coating that keeps out chipping and peeling offering an enduring finish. Interestingly, a single spray can is well-enough to paint 10-12 sq.ft of an area.

Hi, I used personnaly an electric Paint Sprayer which is cheap and work really well. I used for Engine Enamel paint or personal use at home.

The one I used cost me only $67 in Canadian dollars on Amazon. It may cost ONLY $46 US$ and you can choose the paint you like.

I used TopFlite fuel resistant model airplane paint from a local hobby shop. It is the only thing I have found that has survived the toxic Minnesota gas formula. My Model A carb has lasted 8 years, still solid. The Rustoleum on the engine pan underneath turned to goop long ago.
