POR-15 Engine paint, my observations.

[Richard150MPH]

Got tired of the "With ceramic" spray paints.
Hard to control where they go and chips easily/often.
Decided to try POR-15 brush on engine paint.

I like that a brush gives me much better control over where it is applied than a spray.
Flows out very well on horizontal surfaces, avoiding runs on vertical is a challenge.
For the second coat I will rotate the part so that the surface is flat.
Goes on thick enough that if a run really annoys you, just sand it out and touch up the paint.
Still requires at least two coats for full coverage without thin spots.
Only doing the oil pan so far but it looks like the engine block will be easier with the cast surface.
One pint will do more than one engine.

Are you going to paint it another color after, or just leave it POR-15?

I am using POR-15 Chevy Orange.

We need pics...

Probably not until tomorrow, after the second coat.

I gave up on aerosol cans for engine paint. Switched to buying a quart of hugger orange single stage and flatten to taste. I also keep some red on hand for the earlier small blocks. Much cheaper and a base of epoxy ensures good adhesion... but I seem to use more than my share. I'm not a fan of ceramic either. Just another way of cat skinning.

I used the POR-15 Exhaust Manifold paint, didn't hold up.

I used por 15 on my engines because the orange nearly matches my car. About 4 coats 1 quart. Valve covers are regular paint Chevy orange slightly darker.

Did you brush or spray?

 

[Jasons69Chevelle]

Spray, brushing looks terrible,(foam brush it if you can’t spray) I used por 15 solvent and a cheap harbor freight house paint sprayer lol worked good though.

Brushing the block surface is coming out fine.
The oil pan is being hard to get a nice finish on.

 

[1969chevmalibu1969]

Sprayed these with por15. Ended up stripping and repainting

Fortunate that the oil pan exterior cosmetics are not really important.
Not a show car.

You need to get POR-20 for the exhaust stuff. I did my Son's exhaust manifolds in bright silver and just looked today and 7 years later looks like I just did them with no rust or corrosion on them.

It said it was made for exhaust manifolds. IDK, may have been POR20, been a while ago.

If it's the newer stuff that's crap. I was told the thicker stuff was better.
