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) ![]() ![]() |

Cerikote is good stuff. Especially if it's baked on. You can argue the heat form the engine may do this, but I suspect that you will have zero issues with it, as long as the surface has no grease or crud on it. We use a acid pre treatment when we coat to get all imperfections off. Muriatic acid works well and is readily available. This will give you a finish that will not oxidize or stain easily. Aluminum is porous (especially castings), so the surface picks up crap easily.

Aluminum is porous (especially castings), so the surface picks up crap easily. The housing is mag. That's why a paint like cerikote is good. It' can be iffy trying to powdercoat mag. Mahle gas burner wheels are mag and they were primed and painted. They would have looked pretty rough in a short time if left bare. |
