Chuck,
Like I said,"the amin blush is coming". It will suface no matter how many coat/layers there are. The wet-on-wet scheme means you only have to clean it off once. When you've finished all the coats/layers.
I don't go out of my way looking for any trick epoxies. Any name brand will do. I'll keep using the same lamination techniques until I'm sure there is something superior.
I've heard that no-anin-blush epoxies are in reality low-amin-blush epoxies and that doesn't seem to be enough difference to make me change my methods.

"Low Tech is the Best Tech"

: I agree that wet on wet is best, but what about amine blush free epoxies?

: Also remember that amine blush can work its way through more than 1 coat of
: epoxy. If you put on a second coat before the blush from the first coat
: has come to the surface there is a good chance it will come up from the
: first coat through the second coat to the surface.

: Just for the record, I still think it's best to just recoat while still tacky
: or wait and sand. It just isn't worth it to hurry after waiting too long.
