Wet on Wet Painting, what is the timeline to top coat

[cxgvd]

I am ready to repaint some chassis parts during my latest restoration and I forget how long to wait for the epoxy primer to harden before it is safe to top coat.  Conversely, how many hours can I wait and top coat without re-sanding?

 

Thanks, Gary

RTL   or Read the Label if it is still on the can.   I would guess most paints vary.

Or look up the paint spec sheet online and it should give you that info

Every paint has tech sheets available covering exactly that sort of information. Crowdsourcing isn't the way to get correct info on this. The manufacturer knows better than anyone, and the brand of paint matters.

I have been doing a lot of this lately. I look at the label and double the time. That is easier than sanding and respraying.

Be careful. With some of the newer technology paints, waiting too long is just as bad as not waiting long enough.
