Rustoleum does not need a primer, but a high build primer is good for filling in imperfections in machinery. High build primers are available in 1K and if you are unfamiliar with 2K products, that would definitely be the way to go.
Isocyanates are present in both parts of 2K products and require a supplies air respirator to use safely. Organic charcoal filters are not adequate. The problem with isocyanates is that they are hazardous below the threshold of smell, so you can be inhaling dangerous amounts and not even realize it.
