Rust Encapsulator or Self Etching Primer, For engine bay. Options

[bperry]

Got an order of L65K rattle can enamel paint from Tower coming in for my engine bay cleanup.

Which would be better for the Engine bay as a primer for enamel:
Eastwoods Rust Encapsulator or a self etching primer?
I can get the self etch in green which might be easier to topcoat
since its already green.

I'm leaning towards using the silver or Red Rust encapsulator as a primer.
Tower said it was fine for use under their paint and I never want
to do this ever again.

How well does the Rust Encapsulator stuff flow?
I'm assuming aerosol is smoother than than using a brush and
is the way to go.

Anybody have any experience with using Eastwood's Rust encapsulator
under an enamel in the engine bay?

Any suggestions?

depends if your engine bay is rusty or just bare metal. If its nice, just etch primer. If its crusty like mine was in spots, use some por15 onthe rough spots and either buy the prep for por15 over bare metal, or etch primer the rest.
