Engine compartment detailing

While mine was empty I sprayed it all down with "gunk". Tnen used a good scrub brush and toilet bowl brush.
Then heavy dish detergent and water mix and scrubbed it down again.
Then lightly sanded it and wiped it down with the solvent of the pain I was
going to use. I used a hi-temp primer then I believe a dupont paint!
Came out pretty good I think!!!
