How long to leave high build after wet flatting

[Elkie885]

Hi, I'm painting my van with celly and have been wet flatting the high build primer, just wondering how long to leave it to dry out before applying the top coat.
Thanks

as soon as its dry
if its dry enough for wet flatting then no problem

I wouldn't wet flat, dry flat much better

as langy says,use dryrubbing with fre-cut paper
