Painting Aluminum, Spray Can Primers Compared

7 Spray Can Primers Compared Side by Side.

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!

Thumbs up for no music, no filler bs.

Great video. No unnecessary elevator music, barking dogs or air compressor tools making noise. This was a well thought out test and comparison. Well done.

Thanks for doing this test! You have contributed to the DIY body of knowledge and we all owe you a big thanks for this!

All great info. no music, no bullshit. 10/10 mate.

Thank you for doing this! I just want to do a craft project with bare aluminimun, and this truly is priceless! No sanding, having to buy metal etching primer! Just what I needed and was looking for!! Appreciate you!!

this video is freaking pricless.... seriously god bless this man

[cassondrap]

This is literally the best “how to” video on YouTube! STRAIGHT to the point, extremely clear information Without rambling on for 20 minutes! Now, if you could just post some grwm how to make up videos, that would be great 🤣 lol

Excellent video and well done with good presentation on the results. I thought an hour in the deburirng machine would have removed the primer on all of the samples and the test would have been inconclusive - boy, was I wrong. Based on your results, I'm going for the ACE Primer - Thanks again!
Unfortunately, I have no value-able input on what causes the dark patina.

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!

i have used Ace primer before and it is excellent----your conclusion agreed with mine from the start---we primed an entire WWII tank with ace primer and NO REGRETS !!! you are absolutely correct in this program ! thank you

[tenacityforthetruth]

Thank you!!! I must have watched this when deciding on primer for an aluminum threshold. 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. I came across this obscure ACE Primer in my arsenal and thought I remembered it out shining many others. Checked and sure enough it was your amazing test that convinced me. Now I can prime and paint 2 more French Door thresholds with confidence.

Nice job. I'm starting a project that requires painting some aluminum and you've helped me a lot in terms of selecting a paint, thanks!

[glennfelpel]

very nice work this is the kind of thing that is hard to do, your work is appreciated.

[donaldardell]

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.

Thanks for what you've done 5 years ago for us

Thank you for making this video. Its simple to the point and your open to others input. These are the videos that I like to see.

[MIKES]

Andy, thank you so much for making this video! I’ve had great luck with Ace Paint and glad to know the primer preformed they best.
