What primer to use for aluminum
A few parts of the lathe that I am cleaning up now, are aluminum. I
want to repaint it and want to select some primer that would stick to aluminum. Would you have any recommendations. The lathe would generally live a relatively sheltered life. Thanks i |

Might not be available in small quantities. Really, if it's not going to be exposed to weather, any decent spray can stuff will stick well enough. Stan |

Alodyne is another. And then there is acid etch primer. But I think you can get away without using any of those. But scrub the surface with Scotchbrite minutes before priming. If you use a Scotchbrite like product,then clean with acetone after the scrubbing. Products similar to Scotchbrite are likely to leave a residue. Dan |

Get it from an autobody paint supplier if you can't find it elsewhere. Mark Rand RTFM |

In a few hours to half a day it will oxidize on the surface and form its own protective layer. |

If Home Depot, does not carry, most marine stores do. |

The lathe would generally live a relatively sheltered life. Thanks i Surface treatment is more important than primer selection. Find an autobody supply store in your area, get some Ditzler DX-533 Alumiprep. It's available in quarts. Follow the directions, treat the areas to be painted. Just about any good primer will level nicely and adhere well after this treatment. |
