Just listening to the "primer debate " again, which made me think...
What type primer ...Epoxy, 2K, or ???... is being used by the major new car builders of the world?
Aren't some of them being immersed in e coating, especially higher end cars?

the last several jobs i did .. my dodge truck / the pinto / now the stang ... i used the highly recommended urethane hi build yellow primer .. i dont like it a bit better than the old standard red oxide .. doesnt cover sand scratches a bit better ..
I may have answered my own question. I found an article on "e coating" from a company called PCI. E coat stands for the electrolosis process... not the type of paint.
It says they are using epoxy or acrylic paints in the e coat process, depending on the area that the products will be used. Sounds like more use epoxy.
I haven't had that problem... but I really "hose" it on, to the point of almost running... and usually it's 3-5 very heavy coats depending on what I need to block out.Quote:

high end shops have been using epoxy for 10 years or better. urethane primer is for collision work just like lacquer primer .
i have a friend that builds boats air planes and road race bodys he rolls out the first coat of 2k then he blocks them and shoots the primer on from there
. lacquer or urethane primer i never buried bad body or any thing more then 180 grit on body work and finer for paint . a new car body are still dip most of the hi end stuff they must be using epoxy as some get worked over alot i been told so they have some filler primers some of the bmw stuff was epoxy when i did get new parts . when i did a re paint on a striped steel car they were acid etch then a epoxy like DP the a k2 then a tint primer thinner body primer then the k2 something more like a k36 used for a sanding sealer .then sanded out to 600 then to base . shop jobs we just thined out dp but it was a love hate deal for a sealer . i like to shoot over sanded 600 grit as you did not get any chunky looking paint were the paint shifted when the thinnners moved out
