I’m disassembling a 1.7 parts car engine and want to paint the fan housing for a future engine build. After a couple of hours of scrubbing and cleaning I can see metal underneath all of the caked on grease and oil! What’s the best next step cleaning and prepping process before paint? Is oven cleaner ok to use?
Thanks, Jsaum Attached thumbnail(s) |

Have it tumble blasted, but do not paint. Anything that will inhibit heat dissipation should be avoided on air-cooled motors.
This one was tumble blasted and has returned to its original magnesium finish to tarnish again over time. |

This one was tumble blasted and has returned to its original magnesium finish to tarnish again over time. Now I've learned something new today. Had to Google that one. Can you explain the benefit of tumble blasting as opposed to something like walnut blasting? |

This one was tumble blasted and has returned to its original magnesium finish to tarnish again over time. Now I've learned something new today. Had to Google that one. Can you explain the benefit of tumble blasting as opposed to something like walnut blasting? As per one of the tumbler manufacturer's website, "In tumble-blast batch processing machines, all surfaces of components are exposed to impact treatment as the parts gently turn over and over in a slowly rotating tilted basket. This design virtually eliminates component damage due to part-on-part impingement that is so common with “barrel-blast” machines. Our tilted basket generates greater circulation of components in the batch, which not only yields more thorough and uniform coverage, but also makes for a shorter blast cycle – typically five minutes or less!" My local supplier did not disclose the type of media used, however upon completion of the process, the pores of the magnesium are left closed. No need to seal it with clear or paint. |
