Does anyone know of a hardware store type of spray paint (Krylon, Rustoleum, etc.) that is similar in finish to Eastwood underhood black? I have a couple of small spots I have to touch up and I really don't want to spend $20-$25 for a can of spray paint for the small amount I need.

Too bad your not closer I have a couple of cans but the flipping shipping cost is going to put it right there

Krylon Semi Flat/Semi Gloss and SEM Trim Black come to mind; I have a can or two of several different brands & sheens for the little stuff.
The actual sheen of the various blacks varied depending on who made/supplied the part back in the day.

i just got a notice shipping is going to take a BIG jump on the 18th of this month.
i almost won't be able to GIVE stuff away !
i sure hate to scrap stuff, but i guess i'm going to have to now..........

Just in time for ? BBB, SS gets a 3.2% increase but they raise the tax brackets by 7% to offset inflation 🤪🍻
if this is deemed too political just delete it

Whatever paint you select,it is a good idea to apply some to a piece of scrap metal first. After it dries / cures, compare the sample to your car's paint to make sure it matches.
