: What temperature and humidity is the shop? If it's cool and/or gets
: cold at night, it can take quite awile for the varnish to
: harden. Also might want to read Rob Macks guides for
: construction on his Laughing Loon site, not all varnishes are
: compatable with epoxy. Another thing, have to make real sure
: there is no blush on the epoxy before you varnish, nothing
: sticks to blush and if it's there the varnish will never cure.

: Between coats of varnish you only want to sand to 180-220, any more
: and there's not enough "tooth" for the varnish to bond
: to and the layers won't stick to each other.

Temp should not have been a problem as I brought the hatch cover in the house for the last four days to avoid any cold problems. I was sanded with 220 grit, and used non blushing Mas epoxy, thx,,Dan
