Repainting an aluminium engine block
FORD Fiesta Mk6 Saloon

    Hi all,
    I’m looking for some advice on how to clean and paint again
    an aluminium engine block (close up photo of a couple of pieces
    attached): it seems oxidized (is it oxidized? Not sure what the white
    stains are).
    Project is to make a showcase piece.

    To clean it I’m thinking about using:
    – first pass: Gunk 6868 5L Ultra Engine Degreaser
    – second pass: White spirit
    Good idea?

    To repaint:

    I would like to avoid sandblasting or vapour blasting it (too
    expensive), so: would the paint stick to the stained aluminium as per
    photos?
    Any advice it would be really appreciated!

    Thanks,
    Walter

    In my opinion,  it is better to sandblast and powder painting if it is affordable. It will last much more for sure. And regarding the other options, I don’t think they are durable and more likely everything peels off.

      Thanks! 
      I guess an aluminium deoxidizer is not enough in this case…

    I have a homemade sandblaster that I may test (perhaps too hash on
    aluminium?). 
    I also got a quote to vapour blast (more gentle than pure
    sandblasting?) all the 9 piece of the engine (including the engine
    block) for £200 (no idea if it’s a good price or not).
