: this system 3 pamplet i have says no need to sand between coats
: as long as next coat is put down within 72 hours...

: if thats the case sure will make for some ease with laying cloth then filling
: the weave then filling the weave again...

: anyone see any problem with not sanding between coats within 72 hrs other
: than maybe knocking off a few high spots?

I used that schedule in filling my weave and it all went well. Same epoxy. Basically did a coat each evening over three successive days. You're still getting a chemical vs. a mechanical bond at that point.
