Once Epoxy is scuffed is there another time frame to reshoot?

I have a semi Chassis I primed in pieces about 4 months ago , chassis is together now and was going to scuff and shoot more epoxy then paint. Once its scuffed do I have a certain time limit to reshoot or once its scuffed and opened back up if its a couple weeks is that ok?
 
Epoxy re-scuff is nothing like a 2K urethane primer so the answer is no.
However after this amount of time you and only re-coat with epoxy again.
 
Thanks Barry, I was going to scuff then 2 to 3 coats of Epoxy then single stage black, with my schedule its going to take some time to scuff the whole chassis and wanted to make sure I didn't need to rush to get more epoxy on it.
 
I want to confirm this is still the current understanding, If I have a car primed with Epoxy that has been sanded with 600 grit and then sat for a few weeks, it does not need to be scuffed before applying a sealer coat of epoxy then base clear.
 
At my shop and every other shop I've worked at, a three week delay would mean a thorough wet scrubbing with scuff pads and soap at the very least. I've never thought huge delays between sanding and coating application were a good idea. A better idea might be to sand and prime only as many parts as can be done in a reasonable length of time.
 
I’m currently in the same kind of situation too. What is a reasonable time frame to sand before sealer/paint applied. Is a week too long or we talking like hours or just a day or two. Gonna need to time manage hard during paint time.
