Best method to clean empty engine bay
Any recommendations on what product to use and how to go about cleaning an empty engine bay, prepping for paint? Also what color and type of paint should be used (1966 C2). - thanks, mike

Mike - Do you have some thick built-up grease around the steering or suspension parts? If so, and you don't have a nearby steam cleaning facility (I think a lot of them have gone away due to environmental concerns), then you'll probably have to get out the putty knife and scrape away the heavy accumulations. After that I lay down a large plastic tarp, and spray a lot of foaming engine degreaser followed by a stiff brush and then hand wiping it off. After you've gotten the bulk of the grease/oils/crud off, I'd use some 409 or Simple Green and wipe it all down.

I used a couple of cans of spray Gunk, and a power washer. I would paint with an Eastwood under hood paint in a satin black. I used SEM Trim Black and it looks great, but it reacts to gas.......under hood paint is made to be oil, gas, and antifreeze safe.......not sure if it's brake fluid safe.

Another easy question
Have someone else do it!

I've had good results by using Purple Power and a stiff parts cleaning brush. IF you leave it on, it will soften paint, but you were going to repaint anyway, right? Start with a putty knife or similar for the clumpy stuff.

Krylon #1613 Industrial Semi-Flat Black Lacquer is probably the best choice IF the engine bay is still original lacquer paint. Lacquer will lift an enamel repaint. This paint is not easy to find, but there are sources..........and one person has recently been able to get Krylon to again manufacture it for himself for sales.
I can probably get this contact info if no one else can provide. It is also in the archives. I was part of one of the earlier threads on this same subject about a year or so ago.

Lacquer thinner will cleanly remove old lacquer paint. Lacquer thinner may or may not immediately remove/lift air dry enamel. But it should wrinkle up and lift and bubble the enamel paint. Very (very) old air dry enamel or enamel subject to heat (engine compartment) or enamel where a harder was used/added may not exhibit this behavior.....and may be okay. Only way is to test a small area that you know will be refinished anyway.
The newer (fully cured) urethane paints are pretty much immune to anything except a grinder.
I would try the Krylon Industrial #1613 in a small area and see what it does.

Eastwood Underhood paint and SEM Trim Black are also choices. A fourth alternative is to buy a quart of black and add flatteners to produce the desired matte/low gloss finish. John McGraw gave us his recipe for this a year or so ago, and it should be in the archives under his name if you search. But this also requires a compressor and finish gun for best results.
Your choice.............
