: Once the seal

: Once the seal coat is cured, you also have the chance for blush.
: This has always been my� concern. Many of the epoxy
: manufacturers give you a window of time that you should re-epoxy
: to get a chemical bond. After that you can get blush and then
: you are forced to wash it and sand. And now you are getting a
: mechanical bond. Mixing and applying epoxy is the necessary evil
: on a fun woodworking project for me and any step I can take to
: do less of it, I'm happy about. From what I read, I know I'm in
: the minority. I think of it this way, 4 seal coats for inside
: and outside of the deck and hull is a lot of epoxy work and
: clean up to achieve what I'm doing without that.

: The supposed blush-free epoxies (which I use) can blush because I
: have seen it. If your epoxy has hardened and you can drag your
: finger over it and create a trail in the shine, that's blush.

I usually try to do the glass layup the day following precoating, the precoat is cured enough to gain it's benefits and there is definately a chemical bond as it takes at minimum a week for the cure and more usually a month.
