no new pics yet. I have the motor almost ready to go. The project went on hold for a while since other things took precedence. I am hoping to have the motor painted within two weeks or so. I am debating on a color scheme. Silver block/black manifold/black valve with silves stripes or black block and everything else silver with raised black lines on valve cover. I like the second one better. I am trying to keep it simple.'

So i was all set to paint the block today. I used a product called naval jelly to loosen up remaining rust, and then simple green (the concentrated stuff) to degrease the block. After that I hosed it off with a garden hose and a soft brush. I then proceeded to dry it with a leaf blower, and afterwards wipe it dry with a lint free rag. The problem I am running into, is that the block turns gold on me before I can hit it with a rag. The yellow stuff is surface rust. The same stuff that shows up on your rotors after washing your car.
I am afraid that if I paint over it with high heat engine enamel, it will eventually peel. Does anyone have suggestions how to get around this?
It was suggested to me to use self-etching primer, but that stuff is only rated up to 200 degrees. I am not sure if that will be good enough as an engine can reach up to 260 or so.
Any suggestions will be much appreciated..

1. Sand the crap out of any surface rust.
2. Wipe the block down with acetone and a good rag. (Something that won't leave a bunch of lint.)
3. Paint a couple light coats about 15 minutes apart.
If you must use water buy some brake clean. You can spray the crap out of the block after using water. It helps displace any left over water and will help keep the surface rust at bay until you can paint. You need to plan on painting within minutes of cleaning.
Good lukIt could be worse... you could be on fire... or like Chevys.

Awesome job!
My dad overheated his engine the first time he fired it up. Burnt the paint up too... well it turned all brown anyway. LOL.
Watch those engine temps. VHT says you need to break in their paints. You might want to check with your manufacturer.
Good luck.It could be worse... you could be on fire... or like Chevys.

I took out the carpet today and while the interior was clean, the carpet was wet. I also took off the rear cards and found that on the driver side I had water accumulated just behind the body panel. I drained it by drilling a small hole on the bottom of the car., but now I have to paint it so it does not rust.
