Painting of Engine Bay, What all do I need? Options

[RustyWa]

I'm getting close to the painting stage of my engine compartment update. I would like some suggestions on what type of paint I should use.

I stopped at the local paint supply store, they sell PPG products, and talked with the guy there. I'll need to do some spot priming of the bare metal, so he suggested a self-etching primer in a can, an SEM product I believe. For the paint, my car is green metallic, he suggested using a single stage paint. He said a quart of the PPG MTK ($20-$30) which is an acrylic urethane should work good for the engine compartment.

He also said I would need a catylist ($13) and reducer ($20).

So how does this sound for a metallic paint application in an engine compartment?

Also, I will need to weld in a new battery tray/support and a new engine lid hinge bracket. How critical is it to spray weld-thru primer onto the car where these pieces will be welded to? The weld-thru primer at the autobody store was like $20....and I'm such a cheap bastard.

Eric,

I am using PPG on 2-OH! and love the result so far...

Because I had to cut out engine tray pieces, skin pieces over the Long behind the passenger seat and cut out a piece on the firewall, all below the battery tray...Also, I cut enough of the Long to get down in there and coat 2 layers of POR15 on everything I could reach...I prepped the engine bay flat surfaces (anywhere water will sit) with Metal Ready and then two coats of POR15...

My painter is using a primer over that and then of course the paint itself...So I will have about five or six coats of paint for water penetration protection...did the same thing to the new battery tray & support and of course all the welding...

If you want to go out to see the patient, let me know...the doctor is spraying color today and tommorrow...He's in Bonney Lake...

2-OH!
