Another seal or not to seal question

#1
This vette I'm working on has a lot of paint on it, I used the existing film build to level out a lot of the fiberglass by DA'ing with 180 and then water sanding starting with 180 grit and working up. Also have areas of bodywork where I repaired cracks and old collision damage so there's feathered in filler/lacquer primer surfacer. On much of it I ended up using slick sand to get it nice and level.
I was thinking I could use SPI epoxy primer over all this (finished bodywork, primer, slick sand) and block sand it to 4 or 600 and call that sealer for base. Am I correct? Or do I need to add another coat of reduced epoxy as a sealer?

Also, after sanding it with 400 will it be ok for a couple weeks before base? Having to work around my work schedule, paint on weekend etc...

After two weeks old sanding give it a light scuff and then use epoxy 1:1:1 as a light sealer coat, you’ll have better basecoat adhesion and a stronger paint job.

Repairs tend to show up later to some degree, especially in heat cycles and if spray can lacquer primer surfacer was used. If you can get these areas nice & warm a few times without overheating the areas, it will help things to do more of their main shrinking now before final sand.
