I'm restoring an old Duro bandsaw, and I've prepped the castings for painting with a flap disc.
The wheel cover is aluminum. I'm using Rustoleum to paint the machine - can I paint straight onto the prepped aluminum or do I need to use a primer first?

As you can see there is bright aluminum showing in patches.
Thanks for any advice you have.

ALWAYS prime first. In this case, you might also consider metal prep before primer.

Yup, use the metal primer. Using a primer is rule #1 with painting metal, and most everything else.

Ask your paint supplier what the recommended primer is for the top coat you have and use that. Always use products from the same manufacturer. Cheers

You all say primer, primer it will be. Thanks.

As an aside, after several coats of primer, and some light sanding, all those little pits in the cast aluminum will disappear.

I have had good luck with Sherwin Williams Sher-chem. The primer is a bit high, but the paint is reasonable. I actually shot some with a $10 Harbor Freight gun after finding out a piece was missing from my more expensive gun. To fill in all the pits, I use dolphin glaze. It is a 2 part glazing putty and I love it. I got it at a Pittsburg paint store.
