Painting an Engine

[f100matt]

I was thinking about painting my 352 before i put it back in my F100 but i have a few questions.

first, can i use rust killer on the hard to reach spots that i cant grind the surface rust off...

and can i use a normal auto primer to smooth the places the old paint has flaked off or do i need something special??

I generally use a die grinder with a wire wheel, a wire brush and as a cleaner $1.29 Valuecraft Autozone brake parts cleaner.

I do not use a primer. I just never looked for a hi temp one and figure if it failed it would look horrible.

I use strait Hi temp Duplicolor 1621 on my engines, so far so good.

I am having a few issues with my slick's intake though. I had a bad gas leak and it ate the paint. My Fairlane has had its share of gas leaks with no issues. Not sure what I did wrong, too much scale/rust maybe

What worked great for me when i painted my engine was to use easy off oven cleaner.
What i did was to steam clean engine, then taped or covered distr. and carb with a walmart bag, then sprayed the engine with the oven cleaner.
Let that sit for about 30 min then hit it with the power washer again.
It stripped all the remaining grease and paint clear down to the bare block.
I then let that dry and hit it with my engine paint.
Did this 2 years aqo and all i do is rince the engine when i wash the truck, and it still looks the same as the day that i painted it.

Hope this helps,
Wes

Don't hit anything aluminum that may be on an engine (aftermarket valve covers etc).

But, just for fun, spray easy off on some aluminum foil, wad it up into a ball and toss it in the driveway (have the waterhose ready).


I know a fella that had a Corvette show car, decided to use easy off to clean it before a show and hit the aluminum valve covers on it, it etched them and turned them brown.

Sorry to hijack your post, but since we're discussing "Easy Off" I read recently that you could put oven cleaner on the exterior trim (chrome?) then buff it. Anyone tried this? Not sure what the trim is made of.

I've never used primer on an engine, either. Just a couple thick coats of engine paint.

Here's the last one I did...not that anyone really cares, nor is anything really remarkable...I just happen to have a pic laying around with nothing to do.
