I'm looking to paint my engine bay while my engine is out to protect it from rust. I already cleaned it up nicely with simple green and I am going to buy some POR15 rust preventative paint in clear. This: http://www.por15.com/product.asp?productid=6 Anyone use it or have any experience with it? I might paint my underbody as well. I am going to sand down any rust spots then paint over it.
Anyone use POR15 paint?

I have no personal experience with it but one of my co-workers restores Model T's and swears by the stuff. Says it does all it advertises. Only warning he gave was not to get it on your skin as you will have to wait for that layer of skin to come off before the paint will.

I did my whole undercarriage with it. Sandblasted bare and put on two coats of POR-15 and two coats of the black coat over top of it. The stuff is great for chassis but I'd think twice about it for your engine bay. It doesn't leave the kind of finish you're probably looking for. I'd go with a good epoxy primer and paint for the engine bay. Just my 2 cents.

I've used it several times. It's great for using on exposed sheet metal, but once you put it on there, you will never get it off without some serious industrial solvents (don't paint over screws or bolts if you ever want to get them off without chiping away the paint)
I wouldn't recommend using it in the engine bay - parts I had painted and left out in the sun to dry really absorbed and retained the heat - something you don't want in an engine bay.
(BTW I've used this on Model T's too!)

I never thought of that. I have my door bar all scratched up where I slide in and out of the car. Good idea you're right the stuff will take a beating.
I used the acid primer the first time Eric, nasty stuff...
A regular self etching would be much easier and a lot less costic. Only thing is if you miss a spt you can not touch it up till it drys or it will dry dull on that spot, otherwise the bruch strokes disappear and shine.
We we painted my car silver I painted over the POR15 with the base and clear and scratched up the door bar, which I hated. So with the new chassis it is going back to black POR15.

I'm currently using black POR-15 rust preventative paint in the restoration of a '69 MGB. I've used it on the frame rails, floor pans, trunk and fender wells. It is a quality product. I wouldn't use it on an engine block, however. The POR brand offers a brush-on engine enamel specifically for engine blocks. I used this on the MG engine. I know some of you may be skeptical about a brush-on paint vs. spray, but let me tell you, the paint turned out awesome. You can't see any brush strokes at all. The shine is great too. POR claims that their enamel has the highest amount of solids of any paint on the market. I don't know. I do know it does what they say it does. Too bad it's so expensive!

Dont be afraid of a cheaper produxt,its how you apply them that make them look good.I just used some Krylon "Wrinkle" paint for the engine bay,came out pretty good.
But,yea thats some nice paint.
So is PPG whitch we used to paint our car with,outside,in the drive way,with a 20mph wind.

I've only used it once... when I was building up my Fairlane the first time, I put it on the front fenders where surface rust had started (sanded the rust first), as well as a couple of floor pans that I riveted in. I must ahve done something wrong (didn't know you could) because EVERYWHERE I put the stuff is completely rusted out.
They also claim it's sandable (well, used to), which is bull*****. As people said, you can beat it with a hammer and not hurt it... sanding doesn't have much effect. This was about 10 years ago, though... they may have changed the product.

Thanks guys, lots of responses!
I'm not looking for a show car finish. I just want to protect the metal from rust and especially the hard to reach places when the engine goes back in. I don't pop my hood for many people anyway
I would be using the rust preventative paint. I was going to pick up a quart of clear and paint away.

Haven't had the pleasure of using that stuff yet. Maybe on the '87 since it needs some rustproofing work on the undercarriage. Keep in mind if you ever do any paint stripping, give their stuff a try. It really works great and doesn't put off near the fumes that alot of the others do.
I started painting my engine bay today. The other day I cleaned it with simple green and wiped it down good with a spounge and a bucket of water.
I bought a quart of clear POR 15 rust preventative paint. Heres a pic from today:

Can this stuff be applied right over old rust... like without grinding it off? Because my hatch and doors are starting to get really rusted, and if were to grind it all off, it might go right thru... I've been looking into this stuff as a solution...
