: 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?

Probably NOT an issue now, but if you're working in temps/humidity that push the envelope of proper curing on their schedule... you might give it the ole fingernail test.. and if it's hard.. it wouldn't hurt to give it a light sanding.. Just to be safe... Wouldn't take an extra 10 minutes..
