Cool Question on laying paint over fresh primer.

In my early 20's I was a spot painter at local body shops. After the body work we'd shoot primer, let it dry, sand with 220 then spray color.
That was 40 years ago and boy, have times changed!
I just sandblasted my roadster frame and am about to prime it with DTM Epoxy primer. That'll be followed by acrylic urethane single stage silver metallic.

The instructions on the can say I can shoot the color coat directly onto the primer up to 4 days after shooting the primer with no sanding of the primer, at all. Is that how it works now? 40 years ago we didn't have epoxy primer or acrylic urethane. I've been out of the 'auto painting loop' for a long time!

Yes that is how it works now.. no sanding required unless of course you have trash in the primer.. Stay in your recoat window and you will be fine..
