So when is black. Black

[jorgeinmiami]

I painting my engine and cowl which takes mercury fathom black. About $10 a can.

But would not rustoleum gloss black be the same?

Is black not black?

Crayola would disagree

[Xermakius]

The shade of black is probably slightly different. Rustoleum is not the same chemical makeup as mercurys paint and wont last nearly as long. Ive tried it before with an old evinrude, fuel and oil spills will eat the rustolerum. I repainted an entire engine with the oem rattle can paint and used 5 cans. Looked new several years later before I sold it.

With quality of paint aside.

Black paint can be made with equal parts red, yellow, and blue paint mixed together. You can also mix complementary colors such as blue and orange, red and green, or yellow and purple. Mixing blue and brown can also result in a rich black.

All depends on the manufacturers recipe
