Ok, I know it's come up a million times but my memory is lacking in regards to what's the max time I can wait without sanding/scuffing to apply body filler over epoxy. I typically apply epoxy the next day as Barry recommends, but I din't have time the next day...so...how long do I have?..if I do have to scuff to apply body filler, what grit?

Opinions will vary. After 48 hours, I scuff with a red Scotchbrite. Doesn't take much time, and keeps me out of trouble.

red scotch is corse enough to except body filler?...what about not scuffing after 48 hours...problems?

Yes, apparently so.

...what about not scuffing after 48 hours...problems?

It depends. Usually not, sometimes yes. I've put filler on epoxy hundreds of times, and have occasionally seen adhesion problems of unknown cause. Cutting the shine off the epoxy with a red pad fixes the problem.
