Clean the aluminum well, use liquid tsp or similar product, rinse well,
Lightly sand it, to degloss the surface, you can use a medium sanding sponge, apply a quality bonding primer, such as DTM bonding primer, because you are going to a lighter color I would prime all of the aluminum, normally you would only have to prime any bare aluminum, after you prime then apply two top coats of a quality acrylic, you don't want to use oil base, oil base does not have the elasticity to expand and contract, so use a acrylic latex

Why do you think that METAL needs to have a paint that is flexible? I guess you need to inform the stupid car manufacturers.

Its a fact that aluminum expans and contracts, its a fact that latex, has more elasticity than oil base, we paint aluminum and aluminum sided houses every year with great success and a written warranty. We are up on the latest technology, as we constantly meet with service representatives and district managers ect. To learn about the latest advances in the coatings industry.

they use flexable paint on newer cars, not sure when it changed over but thats how you can get a ding and pop it back out.. older cars get a ding and the paint cracks.. I used to paint cars so I am aware of what they are using

Bob Mariani

Oh? I still get sold lacquer.. did not know they are now using Acrylic Latex for metal.... thanks for the update!

There is not just the slightest touch of sarcasm there,is there?

Aluminum siding/trim is a different animal all together than painting a car. Also, a carmade of aluminum is painted differently than one made of steel. The industry standard is to wash thoroughly using a scrub brush and power washer if possible. Then go straight to paint with the first coat having emulsabond added to it. I stopped counting how many houses we have done like that and never have a callback for adhesion issues.

Yup...that's the way to go for sure

Regardless, for this particular project the information you question is correct
Oil/Alkyd/Solvent primers are not the best solution for aluminum substrates
