Normal Alu needs a lot of preparation ie: zinc oxide as a primer before you can paint it.
Anodized surfaces are inert and as long as not waxed/polished etc will remain slightly pourus. Anadization is THE BEST surface preparation before painting. Nothing else needs to be done. Don't expect to be able to get the paint off again though.
Surface.
If it's alkali then you'd have to use a neutralizer, like water, ammonia or baking soda, prior to painting. The pH of the surface has to be below 10 prior to painting.
Yes. I've used it on aluminum as a permanent repair. I'd recommend prepping the surface thoroughly.

Use gripper as a primer before painting your cabinets. I made the mistake of putting paint over cabinets with out gripper and the paint easily chipped and would even scratch with as little as a fingernail when opening a door or drawer. The next time I painted cabinets I used gripper and after 5 years the cabinets still look like new.
No, aluminum cannot be anodized with steel attached. Anodizing is a process that specifically applies to aluminum and its alloys. Steel cannot be anodized in the same way as aluminum, as it requires its own unique processes for surface treatment and coating.
Aluminum can be anodized because it forms a natural oxide layer on its surface that can be enhanced through anodization. Anodization involves creating a thicker, more durable layer of oxide on the aluminum, which improves its corrosion resistance, appearance, and adhesion for paints and dyes.
Anodized aluminum itself is not magnetic because the anodization process forms a non-ferrous oxide layer on the surface. However, the base aluminum material can be magnetic depending on its alloy composition.
To clean anodized aluminum effectively, mix warm water with mild dish soap. Use a soft cloth or sponge to gently scrub the surface. Avoid harsh chemicals or abrasive tools that can damage the anodized coating. Rinse thoroughly and dry with a clean towel to prevent water spots.
Yes, anodized aluminum tumblers are safe to use. The anodization process creates a protective layer on the surface of the aluminum, making it more durable, resistant to corrosion, and less likely to leach into beverages. Just make sure to follow any care instructions provided by the manufacturer to maintain the tumbler's safety and integrity.
Extruded aluminum is aluminum that is melted down and extruded, pushed through a certain 2d shaped hole. This can result in square tube, rectangular tube, an L shaped extrude, and an infinite array of other shapes. Powder coated aluminum is aluminum that could be extruded aluminum, that is cleaned, coated with a colored plastic powder, and then baked so that the plastic powder melts and forms a smooth, nice and even coat of colored plastic over the part. This is basically painting the part. Anodized aluminum is aluminum, again this could be extruded aluminum, but it couldn't be powder coated aluminum, that is put in a chemical solution, possibly sulfuric acid, and then a current is run through the aluminum. This causes a reaction to occur where a layer of aluminum oxide gathers on the surface of the part. The processes is then stop and the part can be colored if desired. Anodozing aluminum gives the part better corrosive resistance and makes the surface tougher and harder than it would have been if it had not been anodized. It does add thickness to the part which can be a downside, but it also is lighter than a powder coat if a paint job is desired.
Anodized cookware means aluminum cookware with an aluminum oxide coating. Don't cook alkaline foods in it; this will eat away the coating. Use non-metal tools to prevent scratching the surface. Wash by hand rather than in a dishwasher; most dishwashing detergents are strongly alkaline and will eat the coating away quickly.
Manufacturers found that aluminum can be anodized to make it stronger, slicker, more durable, and non-reactive with foods. This applies to many types of cookware, including Circulon and Calphalon.Calphalon, a maker of anodized aluminum cookware explains it this way:"Hard-anodization is an electro-chemical process that hardens aluminum. (Hard-Anodized aluminum is 30% harder than stainless steel.) During hard-anodization, aluminum is submerged in an acid bath, then subjected to electrical charges. The result is a chemical reaction wherein the surface of the aluminum combines with oxygen to become aluminum oxide. This reaction is also known as oxidation, a process which occurs spontaneously in nature. Hard-anodization is actually controlled, accelerated oxidation.
Hard anodized cookware is produced for the purpose of stopping food from sticking while cooking. Anodizing is a chemical process that hardens the surface of the cookware to a point where the pan is no longer porous.
After applying polyurethane, prepare the surface for painting by sanding it lightly with fine-grit sandpaper to create a smooth and even surface for the paint to adhere to. Make sure to remove any dust or debris before applying the paint.
To prepare a surface for painting using liquid sander deglosser, follow these steps: Clean the surface to remove any dirt or debris. Apply the liquid sander deglosser according to the manufacturer's instructions. Allow the deglosser to dry completely before painting. Sand the surface lightly with fine-grit sandpaper to smooth out any imperfections. Wipe down the surface with a damp cloth to remove any dust. Now the surface is ready for painting.
There are some documented "lost" technologies developed by the alchemists. Examples include flexible (bendable) glass and methods for coloring metals through (not just surface coloration, as in anodized aluminum).
