Excellent! And at the end there you say this wasn’t scientific, but as a PhD student, I’d say this was scientific. You had a blind hypothesis (not knowing what to expect). You had a method (all pieces were painted and cured at the same time, and run through the machine at the same time). You had steps in your method. You had a control piece, and an experiment group. You produced a set of results. You had a conclusion. That sir, is science. Excellent!

Thank you for this video. I've done some similar comparisons of primers as part of a motorcycle restoration project, although I didn't use a tumbler. While not a rattle-can, I settled on Eastwood's Epoxy Primer. It's Isocyanate-free, lays down smooth, gets great adhesion, and is incredibly hard. Sanding out a run is a real chore. I use a small Iwata HVLP gun. The same primer can can be used as a primer-sealer when cut with more reducer (after body work or using a polyester sanding primer). Thank you again!

The black top coat has held up amazingly but I didn't remember which of the numerous brands I have on hand that I used.

Now I can prime and paint 2 more French Door thresholds with confidence.

FWIW. My understanding is that bare untreated aluminium needs to have an etch primer applied lightly before applying a top coat of epoxy and allowing the epoxy to cure for 7 days. The etch primer has an acid in it that causes the aluminium to have a micro-rough surface which allows the expoxy to grip the surface.

My understanding on paint is that any enamel that contains ammonia creates a chemical reaction between the paint and the aluminum substrate that prevents proper adhesion. I've had very good luck with aluminum prepped with a 80-100 grit sandblaster and etching primer.

Love the video! I would love if you could expand on this idea with other primers and different tests. Primers such as the 2k Epoxy primers in a can, Zinc Chromate primer, Zinc phosphate primer, and the other hard-hitters. And then do corrosion tests, scratch tests. And to expand on the etching of aluminum process, like vinegar to BONDERITE. Just stuff I haven't seen in any other youtube video. Thanks!

@vincevincet1803

The reason the parts turn black is explained in two ways. To understand that, one needs to remember that aluminum "rusts" like iron, just not continuously. The Oxygen layer that forms creates a hard, clear, protective barrier. That Aluminum Oxide barrier prevents paint from sticking (hence etching). The 2 things that cause color in aluminum (especially black) are this: acids, detergents, etc., causing pores changes and thickness of the oxidizing layer (which can become greater in surface area due to pitting or scratching). Aluminim forms a hexagonal cell-like layer with a pore in the middle. Pore distance affects refraction. Here's a tech article portion on the process: "Different colors can be explained by different degrees of reflection and absortption of sunlight components by oxide films and the aluminum surface. White light has different components which can create a spectrum of colors either naturally (rainbow) or in a laboratory with the help of diffraction or dispersion. If the oxide film does not absorb any component of light and all components are evenly reflected by the aluminum surface then the film looks colorless (white). If oxide film absorbs all components of light without discrimination then the film looks black. If a specific component of light is absorbed better than others, then the combination of reflected components without the absorbed one will create a non-white color."

I worked in automotive making aluminum crash management parts, some of those were coated or plated, for certain they have to "key" the surface so that the plating sticks. I am curious if this translates to paints as well, like the "patina" version here has some characteristics of "keying" to help the paint stick to the surface.

Aluminum is very hard to paint I have a project that I'm working on and I tried to paint it and the paint you could just doesn't take much to scrape it off with your finger nail so I stripped it off and I picked up some vinegar about a gallon and I put it in a pail and I let it sit the aluminum sit in the pail and I hooked a battery charger up to to one one part of the aluminum and I had another piece of aluminum in the pail and I let it sit there for about a couple hours and I it formed a fuzzy coating on the little part that I wanted to paint I use some DuraCoat self-etching primer and some dura coat regular paint it seems that I can't scratch it off I'll have to see how it stands up

Well it looks like the pores the media release “gunk” plus the tank walls are causing the issue. As you continue to tumble the part is creates a ruff surface that allowed the paint to adhere better. A light acidic solution could remove the “patina”.The only other solution would be to Anodizing -it protects them for saline corrosion agents as well as abrasion. Additionally, they can be tinted in many different colours to suit your application.

As a heads-up to anyone using Dupli-Color self etching primer, our local auto body supply shop informs me that it must be covered with a "blocker', another coat of ordinary primer, or it will attack and bubble the topcoat in about a years time. And he was so right because I had already painted something without the blocker and it got screwed up and rough after awhile.
