Did I miss the induction time, or did you really mix and spray? I thought there was a 30 minute induction time before spraying. If so, and you did not let it sit for 30 minutes, why and what are the effects long term? Thank you for your input, and I apologize if I missed it in the video.
As others have mentioned you need the 30 min induction time. Pretty sure yours will flake off as you basically just thinned the base and sprayed it on. It changes color to a slightly deeper green as it lights off. You can watch it work.
A spray gun is overkill for this primer to go on well. Use a primer pistol. Mix in the same container you shoot from - a film cartridge. I've mixed and shot as little as 1/2 oz all the way up to my largest panels. It goes a long way. I measure it out using 1oz syringes, no need to run thru a filter. No spilling as with your pot lid pourers. Clean up is with acetone shot thru the pistol before it dries; wipe out the cartridge and its done. 10psi is all you need, maybe 15 with the pistol. No more or youre just bouncing primer off the part.
I've posted a bunch on this previously. Akzo is bullet proof if done right. You did wash and scuff your parts first right?

The most basic version of Bernoullis principle - just like we did as kids in kindergarten blowing across the top of a coke bottle to make music.
I had to tweak mine a bit, but basically the copper tube you can just see sticking up is soft soldered in, so just move it up or down in the sleeve to obtain the best pressure drop across the top. I also took a small file to chamfer the copper tube top slightly away from the air path to shape the spray fan.
When I got it, it needed 60psi to get any draw and was abysmal to non-existent. After the small tweaks above, it picks up paint at 10psi and a nice round spray pattern, just like a rattle can.
Cheap, simple, bullet proof with Akzo. Clean up with a acetone shot thru it and put it away for next time. Takes all the hassle out of primering (for interior parts).

Anyone used this particular Akzo primer (463-12-8) as an exterior primer in their final paint system? What is it compatible with? Even in the Akzo line, I couldnt find where its called out as part of a system they provide.
Would you post a photo of the tube? It would be nice to have a starting point.
I have to use high pressure as well.
Larry - I'm no good with the various photo hosting sites, but if you wanna PM an email Ill be happy to send you as many thousands of pictures of the tube as you'd like. Then if you'd like you can put up the pics.
Mani,
Please see your PM regarding the pistol.
Best regards,
Michael
Mani,
Time finally allowed for us to implement your recommendations on the primer pistol. They worked like a charm. Thanks!
