I am rebuilding an engine which has been in a fire. All meltable parts melted and left its traces on the aluminium engine. I tried to clean it, but did not get the required result.
After Soda Blasting the engine it is clean, but dull (not shiny).

To give the engine a good look I am considering to paint it.

Which paint should I use?

 

I would not paint it - my personal opinion - I quess there could be problems.
Who care's about a non shinig engine? All an engine is supposed to do is delivering driveable power at high effiency - quiet simple...

 

I do

 

Frank,

Saw once here a 951 engine block which was painted with those special coatings which looks almost like silver. They also help with heat transfer.

Check out this:

Their products are available here in Finland, so i suppose you can buy them as well in the Netherlands.

 

How about a fully cermaic coated engine?

 

It's funny but I wanted, for the longest time, to consult the PCA guru John Paternek (sp?) and ask if our engines were ever painted ... ?
I say that because I have noticed that where there has been intense heat i.e. ( headers, down pipe ) the block seems to show a bit of dulling [ it's just not as shiny a sliver as the rest of the block ] I understand that Wurth makes a *** kicking silver paint but I have no idea if that would wk
I thought that when you soda blast aluminum that it looks as if it were new
I was surprised to hear it was flat and dull ?
I too, would like my block looking its best ...
I guess that's why they call me Crazy
Regards
Ed

 

I've checked out the Wurtz info available on the net and it seems like the right product for my "problem".

This is what the engine looks like after Soda Blasting:

 

The soda blasting looks good! You could also powder coat it.

 

Now that would look too nice to put in an engine bay.

 

This is plain old Duplicolor 1500 degree aluminum paint. About 4 bucks a can at the local parts store. Just make sure everything is clean and dry before you paint. I've had this stuff on an aluminum intake on 'Stang' for about 15 years and it still looks as good as the day it was put together.

Great info, Thanks!

Will post pictures as soon as the painting is done.

 

How about a heat emiting coating? It's applied just like a powdercoat but will accelerate heat dissipation.

Musche- I really like the "positive" red on the PORSCHE lettering on the cam tower. Most engines just have the paint sanded off to bare aluminum.

 

I have my Intake manifold, brake calipers and oil pan coated with this stuff. It's pricey but the test data shows good promise....we'll see when it's all together and in the car.

 

The result so far:



I have used Motip Engine Paint (Motip = Dupli-Color)
